Allow people to occupy the same square while standing up

[Weavel]

Currently only one dude can stand in a square, and Help intent either goofily shunts them to the square you were in, or rudely pushes them out of the way. No intent lets you just walk past a guy.

Allow people on Help intent to stand in the same square, offset their player sprite to show they're walking around them/standing beside them, and begone with the dorky movement systems of aeons past.

Also: Two people in the same square? Walking into them should push one of them outta there.
