Aiming to implement the framework oranges has detailed in https://tgstation13.org/phpBB/viewtopic.php?f=10&t=19102
Moves canmove to a bitflag in a new variable called mobility_flags, that will allow finer grain control of what someone can do codewise, for example, letting them move but not stand up, or stand up but not move.
Adds Immobilize()d status effect that freezes movement but does not prevent anything else.
Adds Paralyze()d which is oldstun "You can't do anything at all and knock down).
Stun() will now prevent any item/UI usage and movement (which is similar to before).
Knockdown() will now only knockdown without preventing item usage/movement.
People knocked down will be able to crawl at softcrit-speeds
Refactors some /mob variables and procs to /mob/living.
update_canmove() refactored to update_mobility() and will handle mobility_flags instead of the removed canmove

rscadd: Crawling is now possible if you are down but not stunned. Obviously, you will be slower.
/cl
Refactors are done. I'd rather get this merged faster than try to fine tune stuff like slips. The most obvious gameplay effect this pr has will be crawling, and I believe I made tiny tweaks but I can't find it Anything I missed or weird behavior should be reported.
cl Floyd / Qustinnus (thx to mrdoombringer for sprite + idea)
add: The clowncar now comes with an inbuilt cannon that can be activated by emagging its circuits
fix: cars can only kidnap if they have the CAN_KIDNAP trait
fix: removes a dot too much in a to_chat in clown car actions
/cl
balance: The Clown Car can no longer move unrestricted in zero gravity environments.
balance: The Clown Car now costs 20 TC to purchase.
This PR was done at the request of @vuonojenmustaturska. I renamed entered.dm to sealed.dm because it's where the sealed subtype is defined and it's primarily used for procs specific to sealed. The balance changes were Naksu's idea. I definitely think not being able to move freely in space is a good change. I'm ambivalent about the TC, but the item felt like a gimmick that you should fully commit to like His Grace, and the free space movement + 4 TC space suit was a bit cancerous.
