Movables without density tend to get stuck on walls while dragging.

[haukeschuemann]

Reproduction:

Drag any movable atom without density around a tight corner. It tends to get stuck on a wall, preventing further movement. Good atoms for testing include open lockers or roller beds.

This does not happen if the atom has density, like with closed lockers or crates

Might be related to #81

Definitly related. Bots stopped getting stuck after I gave them density

Not fixing this one in the initial release. Making dragging fully featured and robust deserves its own project

Turns out that #81 is not related. This is another bug where ai controlled mobs without density also get stuck on walls but for other reasons
