* Map Bugfixes

-	Fix for mislabeled c_tag cameras, first deck
-	Fix for mislabeled c_tag cameras, second deck
-	Fix for poi crashed containment shuttle mapping issues (terrain generation)
-	Fixed wrong floor type on skipjack
-	Fix for scrubbers pipe, central substation
-	Fix for air supply pipe, chapel
-	Fixed scrubber pipe, Engineering Drone Fab
-	Fix for air supply pipe, Prison Wing
-	Removed redundant supply and scrubber pipe, Security Auxiliary Dock
-	Fix, Fore Aux Dock airlock pipe.
-	Fix air supply pipe, library
-	Fix, scrubber pipe, coffee shop
-	Pipe fix, Medical maint
-	Fix, supply pipe medical secondary storage
-	Removal, redundant supply pipe, cargo maint
-	Fix, virology scrubbers pipes
-	Fix Xenobio and Xenoflora missing atmos connection to the main outpost
-	Fix, missing atmos connections between Main outpost telecoms and main outpost atmos
-	Fix for missing power wires, HoS Office, Warden Office, Heads of Staff Meeting Room
-	New, random mouse spawner
-	New, random mouse spawners added throughout maintenance on the station (maybe too many, maus station 13)
-	New, 30 sheets of lead added to engineering
-	Fix, POIs should now be rad protected and characters won’t be affected by the radiation event

* Fixes Lead Walls (#5562)

A material's ``radiation_resistance`` was never considered for calculating a wall's cached resistance to radiation. This fixes it. There is another issue involving r-walls not being better at stopping radiation than their normal-wall counterparts made of the same material but fixing that involves a lot of number adjusting to avoid the SM engine from getting twice as protective.

* Rig and Spacesuit additions

- Added the 'military' Rigsuit from Bay.
- Added 'pmc' rigsuits
- Added exploration and pilot voidsuits along with alternate sprites (alternate sprites done by Naidh)
- Addition of suit cyclers for exploration and pilot voidsuits

None of these suits are currently accessible in game outside of admin bus. Currently only the pilot voidsuits have other species sprites. Exploration suits are missing sprites for Teshari (Naidh made some for their alternates but I have to add them) and the rig suits are human only. This is to be fixed in the near future, just wanted to get the make workload actually in the game first.

* Dermal implant doesn't cover hair

* Tweaks emitters and Pacman

* Adds the Biopsy Scanner to the Surgery Kit (#5589)

* Adds the Biopsy Scanner to the Surgery Kit

Since it's actually used in a surgical operation, it should proooobably be in the kit. Iunno if the kit is really used here aside from antag shuttles, but they might as well have it.

* Added a missing comma

Missed a comma, might be what's causing issues. Iunno. It worked flawlessly in dream-maker.

* Adds some Holy drinks, and Promethean-safe drinks / acclimators. (#5574)

* Adds some Holy drinks, and Promethean-safe drinks / acclimators.

* Carbon + Water + Oil = Sludge

* Framework for Custom RIG sprites.

* Fixfix

* line ending

* Text for handheld plushies when poked

Plushies now make sounds when poked. Squeak!

Ported from https://github.com/VOREStation/VOREStation/pull/4231

* Shotgun cycling animation framework
This adds the possiblity for empty sprites on all shotgun/pump/thing and for cycling animations.
https://cdn.discordapp.com/attachments/407267031562453032/488751327531368481/2018-09-10_18-43-05.gif
This particular weapon was made by a friend so i'll wait for their permission before porting it in.

* Add an animated rifle.
Nothing is particularly impressive except the animation.

* Fixes some bloodloss bugs

* Move almost everythign food related into the kitchen module.
Not moving reagents and tools.

* Minor issues fix.

* Remplace sprite hammer with pickaxe
This particular hammer had been sitting 'waiting for sprites' for 4 years at least. Could be a lot more really.

Fixeshttps://github.com/VOREStation/VOREStation/issues/4183

* Fix mislabelled posters.
https://github.com/VOREStation/VOREStation/pull/4310
https://github.com/VOREStation/VOREStation/issues/3597

* Remove kobold.dm
This file has no sprites and is used nowhere. It does have some kinda cute emotes but without sprites it's useless and has been since 2017 and maybe much longer. I haven't found any references of it's origin either.
~~maybe virgo will do sprites i dunno~~

* Fix yes emote not working correctly.
It's a lazy fix but it works.

* Fixes chem master dumping reagents.
Previously, if you used a bluespace beaker and transferred all of it's contents, the chem master buffer would silently drop all of those chemicals without warning.

* Fixed smes terminal construction requiring more cable than used.

* Fixes laptop blocking grown adults.

* Fixes several typos with oxygen_pump.dm.

* Fix the condimaster not working.
Previously, you simply couldn't make any condiment using this machine. Now you can. There was just missing template which is back in with this PR. (Thanks aronai.)
This means you should consider remplacing it in your kitchens.

* Remove intensity from chemistry machines.

* Add a noise for mining scanners.
This should affects all devices using it too.

* Prevents people from HREF exploiting around the R&D console.

* Lock has a check already, so remove that.

* reeeeeeeee

* Fixes missing sprites when excavating rocks

* Xenoflora and Xenobio House Move

- Moves Xenoflora and Xenobio stationside, on first deck. Leaves the old labs still up planetside for the time being.
- Minor bug fixes, missing lights, mislabeled lockers in robotics, floor decals.

* Changes << to to_chat at request.

* wax staxs

* Fix plastic ashtrays only holding one butt. Now they hold 4butts.
jeez bill.

* Move surgery caps into their own selection.

* Fixes maploading

Imagine you're on the last iteration of this loop, you've done the final column of X coordinates and you're going to set maxx.
Would you want to set it to where you are now, the final X column... or would you want to add ONE MORE beyond the template size for some reason then set it to that?

This bug causes all templates that are the size of normal maps to fail to initialize any atoms if your template is the size of your normal maps, because it tries to obtain a square of size minx, miny, minz, maxx, maxy, maxz to initialize, however maxx is nonextant because it exists outside the bounds of the world. It also causes all submaps to initialize an additional column of atoms twice, or not initialize any if they spawn against the right edge of the map.

* Graves (#5622)

* Adds support for closets storing closets, and graves

* More Grave Things

* Chnglog

* Polaris Vision Tweaks

* Fix a couple of ticket bugs

Don't show admin character names when they reply, and this proc appears to take different options on tg, so was fixed here.

* Prevent people from removing papers from any distances.

* Removes maintenance access from cleanbots

This should stop them from wandering into maintenance never to be seen or heard from again.

* Remove very annoying midi tools

* Magazines improvements (#5666)

* Give sounds to emptying magazines

* Clear some trash in the saber magazines

* The magazine NOW behaves correctly.

* The second half and more casing noises.

* Fixes map and makes everything compile.
