broke the collider

Certain objects become antigravitational to certain other objects
sometimes...don't know why yet, think it is something to do with loops
and/or X/Y values being -/+ ??
added item to todo

Fix mass location (when colliding, all mass is instantly moved instead
of preserving mass location)
added junk to the junk
commenting things to fix
code readability, minor changes, hopefully fixed collider
collider fixed (except deep impact bug), extraneous code

There is an unnecessary if in there, and possibly a second unnecessary
if, but that would probably break gravity.
collider fixed for sure (except deep impact)

Typos! X's where Y's should've been!
code readability, error catching

and collision logging for ignored collisions
and the fixed collider seems to have somehow found itself in the master
branch
