About The Pull Request

Mostly backend fixes. Turns a lot of movement code (which was in massive procs) into signals. Code improvement and performance stuff is the primary focus here.

Mostly effects:

• stuff that check or effect what position the player-character is in(buckled, lying on the floor, standing up)
• bodypart disabling in its entirety basically
• health states (unconscious, soft crit...)
• stuff that checks the state of limbs (either being handcuffed, disabled, or amputated)

I also converted a bunch of overused redefines stuff into setters.

Why It's Good For The Game

Clears out a lot of code debt. Should make movement a lot more performant(which is definitely a goal if we want to transition to smooth movement eventually), and should also fix janky movement shit at higher server loads.

Code is a lot more legible, too. The whole mobility_flags thing was CBT to try and code with in a previous pr of mine, so this is a bit personal.

This PR contributes to:

• [Bounty] Get our bodyparts/limbs/organs up to date with TG limbs. #7213

Testing Photographs and Procedure

Screenshots&Videos

Flew off a two floor drop, limb disabling seems to work as expected.

Blindness performs as expected

To note, I left most of dwasint's blindness stuff out, because Racc is already doing that in #8204

DNM until #8204 (or testmerge, bacon)

Mobility and status effects of this PR rely on blindness improvements of that one.
