Get rid of the unnecessary unit collision.

There is no need for unit collision in a game like this and all it is doing is ruining more and more of the fun. There is no point in having a dodge roll, either if I am just gonna roll in place while spamming it because 1 singular white enemy blocks me. Get rid of the unit collision and the game will be a million times less frustrating and a million times better while still being "Path of Exile".
