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.

- Add additional can_atmos_pass value ATMOS_PASS_PROC which indicates custom behavior requiring calling the CanZASPass proc.
- The benefit being for the other three values we DON'T need to call CanZASPass at all! We already know the behavior without the overhead of a proc call.
- Obviously any atom with can_atmos_pass = ATMOS_PASS_PROC cannot now call ..() in CanZASPass() since the default behavior would be to (recursively) call CanZASPass()
- This required re-numbering the constants, so I also fixed all code that assumed particular values for the constants.
- Switched all types which overrode CanZASPass with custom logic to be can_atmos_pass = ATMOS_PASS_PROC
- Changed /turf/c_airblock() to skip calling /atom/movable/c_airblock() for the three can_atmos_pass values that don't require calling the proc.
- CanZASPass is supposed to return boolean. Nobody noticed this bug because ATMOS_PASS_YES and ATMOS_PASS_NO happen to be defined as 1 and 0. But thats not a good assumption to make, so lets fix it!
* Large amount of work; Animal taming, shearing. Random animal spawns on sif grass/forest turfs. New PoIs, thermal poncho.
* Combat drone DMI moved to drones folder. Mining Drone subtype added. "Tameable" with ores, will collect and store ores when not in active combat.
- Adds circuit boards for shuttle consoles. (Ferry, Multi, and Overmap).
- Deconstructing a console saves the linked shuttle tag in the board for when it is re-constructed. New boards start blank but will auto-link if you build the console on a shuttle.
- Boards know what type of shuttle they can control and will only auto-link with a shuttle if it is the appropriate type.
Note: By default the only mapped-in shuttle consoles that are deconstrutable are overmap and multi shuttle consoles. For any others, consoles built mid-game will be deconstrutable but the mapped-in ones will not. That way the arrival, escape, supply ferry shuttles etc won't be messed with unless the mapper specifically chooses to override and make them that way.
* Port ParadiseSS13/Paradise#2100 - Saycode refactor
* Removed unused old carbon slimes code
* Port ParadiseSS13/Paradise#5099 - Saycode part 2
* Ported ParadiseSS13/Paradise#7170's /datum/browser Check Known Languages
* Port ParadiseSS13/Paradise#9240 - Get rid of alt_name in favor of GetAltName()
* Port ParadiseSS13/Paradise#10330 - You can now use multiple languages in one message
* Addressed Atermonera's review.
Translators now print the full message if they find any languages within the
message that the user doesn't understand, minus languages it cannot translate.
Additionally, the combine_message proc has been significantly simplified
by eliminating an ugly tree structure with the help of a little helper
proc.
The removal of the extra span inside each piece doesn't seem to have
visually changed the messages in any other way than changing where the
wordwrap happens, strangely enough. Must be something in IE's code being
picky about invisible elements. On the bright side, it splits *later*
than it did before, thus reducing the lines a message will take up by a
tiny amount.
Also, a bunch of things now have the 'filter_say' class from
PolarisSS13/Polaris#6998. Since span classes with no definition are
totally valid and just don't do anything, this PR does **not** depend on
that PR being merged first.
* Always gotta be one
- Please fasten your seatbelts, this will be a long one as it joins few older Bay PRs into one.
1. Ports https://github.com/Baystation12/Baystation12/pull/12626
- SMES units may now be damaged and destroyed. Charged SMES units fail quite violently. Damage can be fixed by welding tool.
- PSUs completely refactored, ghetto variant no longer exists.
- Cell rack PSUs now can be considered a hybrid between large battery charger and a SMES. They actually use the cells to store power (so you can hot-swap the cells to get more juice simply via the UI without deconstructing the whole machine), but in comparison to SMES have poor throughput and capacity in general (cells are simply too small). They are also somewhat limited in configuration options (lacks the precision electronics of a SMES). Better matter bin lets you put in more cells, up to 9.
- Cell rack PSU also has a mode that allows charge-balancing all inserted batteries (moves energy around so each battery has the same charge %)
2. Ports https://github.com/Baystation12/Baystation12/pull/11977
- SMES units now have full load balancing capability, getting rid of that annoying "One SMES charges at full, other SMES gets nothing" problem. If insufficient power is available on input, all inputting SMESes will now charge at same percentage. If more SMESes power a single output, they will all output equal percentage of their setting.
- This appears to have a pleasant side effect of fixing the issue where SMESes could starve APCs of energy. SMESes are ALWAYS last to input power on a powernet.
- This also appears to have fixed weird values displayed in SMES output/input load readings in the UI. By weird values i mostly mean inputs/outputs actually higher than the SMES is set to have.
3. Ports https://github.com/Baystation12/Baystation12/pull/18137
- SMES units (and subtypes, therefore effectively also PSUs from previous entry) can now have more than one terminal. This effectively allows a setup where two (or more) sources feed a single SMES, which then feeds the output. SMESes can not exceed input setting even with multiple terminals.
- Typical example of use in practice would be SMES that runs something important (for example an AI, telecomms, pick whatever you want). It could have one input from the power grid, and second input from a PACMAN generator set up nearby as a backup. Before the generator would have to be wired into main grid, therefore main grid would siphon off power from it. Now the generator can be separate and dedicated for whatever use you want.
* Adjust map_effect interval loop
We have those things you wanted now. Also bumped check time to 5s because 3s seems a lot for the repeated player list iteration. Not horrible but still.
* Also adjust pinpointer because it's not great
* Add a missing span in pinpointer
* Forgot a couple things!
