* Allows organics to self-surgery after standing still for 5 seconds. It follows the same rules as normal surgery.
* Confirm-by-delay for self-surgery steps.
* Verb to toggle self-surgery.
* Add log.
ACTUALLY fixes problems with borgs permanently breaking their syringes and being able to put modules into potted plants, which causes unwanted fuckery.
Reverts #7560
Adds a HUD for observers
Adds a HUD for rigs and mechs
Adds up/down buttons for AI hud
Add more tg style alerts
Fix some bugs with the tg alerts
Improve icon_states usage by caching it
Redo how respawning works, add a button to ghost hud for it
* Fix a typo in a verb.
* Add straffing to mechs. This took my entire morning goddamnit.
You now have a straffing verb. Very convenient to shoot while firing back.
Thanks to @drexample even if i didn't use all that much of the original code i stole.
* Change straffing to strafing.
* Correct an oversight.
* Add a variable that determines whether or not you are in a mech or fighter at the moment.
* Rework a lot of mech code backend and add clickable buttons.
- Gygax overload, Durand defence mode, phazon phase, marauder smoke, zoom and thrusters have been made into modular things. Just put the 'smoke_possible' var to get those actions.
- Move most abilities that aren't for default mechs to 'Mecha_actions.dm' for less huge of a file. Marauder abilities to be moved shortly.
- Lot of verbs have been broken into procs such as toggle_lights() now being a verb refering to a lights() proc for easier work later on.
- Delete some movement code duplications.
- Changed the smoke system to be more up to date, inspiration taken from the cooking machines.
* Space out some things for ease for reading.
* Improve the damage readout for mechs on examine
* Improve speed boost code to an easier to modify version.
* Deleting a couple few forgotten debug messages.
This adds throw_alert() and /obj/screen/alert, a system that allows you to do custom hud alerts for any variety of things from "You're too cold!" to mecha status indicators for the pilot.
There's quite a few things that actually got replaced; the
fire/oxy/tox/co2 alerts are all now just alerts, as is nutrition. There's also a number of new alerts, such as blindness, highness, legcuffed, buckled, handcuffed, and probably some more I missed; read code/_onclick/hud/alert.dm and see for yourself!
Additionally, a number of tweaks have been done to resisting code, to make it so that there's an indicator when you're buckled or handcuffed, and can just click the alert to start resisting. This includes a refactor that combines the logic for lockers, holders all into one proc, called container_resist().
Also, the health and internals indicator got moved down one tile each. Needed room for the alerts. If we add the oxygen tank action buttons from /tg/ and remove the internals indicator, the health indicator can go back where it was originally.

This adds a system for picture-in-picture UI windows using
vis_contents. Essentially, it allows you to make UI windows that show an area of turfs. It also refactors how cameranet visibility works.
Currently, this is implemented on AIs. They gain two new UI buttons - "Enter Multicam Mode", and "Create Multicam". When they go into Multicam Mode, they see a background of animated binary numbers, and they are allowed to create an infinite amount of these picture in picture windows, which subsequently creates an AI Eye for each one. They are able to control each AI eye individually, by first clicking on the PIP window to select it as "active" and then using the normal arrow key controls. The PIP windows can be freely resized and moved around the area.
You can control everything inside these PIP windows EXACTLY the same as you can using a traditional AI Eye, as demonstrated below.
For admins, there is a config option to disable PIP entirely - simply set `var/multicam_allowed = TRUE` to FALSE if you wish to disable it from being used. (Please be reasonable.) <3
You can see an example of how this works here:

AI Multicam functionality.
Do note that if the lightbulb in the AI core is busted, the multicam room is dark(er) than it would be, but you can still see your camera windows just fine. (I'll probably fix this later.) It only affects the "matrix" backdrop, the PIP windows are still fine.
This has been runtime-tested with the latest `master` revision and produces 0 runtimes, and has no noticeable impact on server CPU usage.
Polarisport is here! Port of https://github.com/VOREStation/VOREStation/pull/7752
The body zone selector now indicates which body part you are about to select when hovered over, and the hover inventory indicator basically shows where you are trying to put an item, and then shows an item ghost in red or green, giving visual feedback as to if that item will go in the slot or not.
Gifs of this in action:

Body Selection parts.

Inventory Icon Overlays!
Credit goes to @ShadowLarkens for original port to Paradise and assistance with port.
Fix an issue whereby when reconnecting to the server after disconnecting/losing connection your internals HUD element will always be off, even if you're actually still breathing from a tank.
Now it checks & shows the correct state so you don't panic after lagging out IN SPACE AAAAAHHHH
- Port based on Baystation's implementation and customized for our code and usages.
- Switched space icon_state permutation to a "dust" overlay that is permutated the same way. As an overlay, the dust can be *above* the parallax planes. Space turfs are now white to allow skybox to BLEND_MULTIPLY onto them.
- Added skybox hud effect that replaces background space turfs with an image moved to create a parallax effect.
- Added skybox subsystem to generate and manage skybox parallax images, and lots of images for it!
* Mobs can be incorporeal
Prevents step noises, getting shot, etc. Basically living ghosts. Feel free to add more places this should check, but I think this is a majority.
* Fix missing incorporeal floatyness
* Combat Mechs Can Punch More Things
Removes the var to check for the 5 things it can attack, instead it can punch anything (but not everything will take damage).
Gives punching objects a check so you don't accidently smash something without meaning to.
Gives closets and canisters a proc to take_damage so they'll actually get smashed by the mechs.
* Take_Damage Boogaloo
* More take_damage Stuff
Adds click delay on attacking barriers.
Proper noises when attacking material doors and barricades.
More stuff can be broken by mech punch and simple mobs.
* Adds changelong
* usr to user
