Chair Shimmy

[kugamo]

About the pull request

This PR lets you shimmy past people seated in immovable chairs..
While occupied movement into the chair tile is blocked in columnar direction, have to move up and down rows.
Occupied dropship seats only block movement from behind, and the back of the seats there anyways

Also I removed an unnecessary variable from chairs, since beds have a similar variable already that can be used.

Explain why it's good for the game

QOL: Makes it easier to find a seat, and adds a bit more organization to dropship seat behavior as well. The shimmying component is neat. :0)

FIX: Currently if an object that shimmies stuff is destroyed shimmied mobs dont have their pixel_x/pixel_y/layers reset back to normal. This PR also fixes that

_{no ulterior motives}

... itd be nice for if perhaps two dropship seats were vertically aligned in a 1 wide room 👀

It doesnt make you say anything while shimmying, I just did that on my own for the demo. Just in case someone was worried
