About The Pull Request

As the tin shows, adds leaning to the game.

Ports the following TG station PRs:

• The Leaning Update (and Density Refractor) tgstation/tgstation#76704
• Fixes getting stuck in the leaning condition when you try to lean facing the wrong direction tgstation/tgstation#77002
• Fixes leaning runtiming from non-carbon mobs, adds a slight animation to the effect tgstation/tgstation#78847
• Changes wall leaning into a component, makes windows leanable #2 tgstation/tgstation#87390
• Teleporting while leaning now makes you fall on your face tgstation/tgstation#88215
• Improves code for leaning tgstation/tgstation#88494

as well as a plethora of modifications from me in the component of leanable.dm which includes falling if the airlock you're leaning on opens, as well as adding the ability to lean on computers, airlocks.

is there a reason why leaning sometimes fails here?

Falling when the airlock should make you fall into the airlock. It doesnt make sense to fall forward on something you are leaning on, yea?

The south leaning looks really bad ngl. I get why it should still exist, but is there something you can do to make it look like the spaceman isn't on top of the wall?

Two people should not be able to lean in the same space.
