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.
