Fix oversized block collisions

Browse Source 
We went thru a bunch of effort for this fix, but its finally been patched.
In the meantime I ported jellysquid's latest changes to entity collisions which also work completely fine.

Thanks to Simon ( @smonnnn ) who is also going to be the co-author of this commit cuz he was the one to properly implement the problematic patch .
These changes should lower your mspt.

Fixes #165 
Fixes #178
