Wheelchair qol (#82968)

## About The Pull Request
Lets you pick up wheelchairs while resting, and lets you place
wheelchairs on adjacent tiles, much like medical roller beds.
## Why It's Good For The Game
Makes life just a little bit easier. Barely being able to move is
already enough of a downside. I think allowing the little bit of extra
independence being able to pick up your own chair (without just finding
or making a basic chair first) offers is justifiable.
And being able to place the chair a tile away just saves needing to
pixel hunt or shuffle around to buckle yourself.
