Title: Box2d unit fixes

More unit fixes collected and updated over time.

I checked against the official Box2D documentation and worked on making sure units were synced up.
Documentation was also updated to help show conversion rules in action.

The commit to update the arbiter may need to be reworked since I wasn't entirely certain on how the arbiter should be linked to the world. Since it appears that there is only 1 arbiter instance created (the Lua 'new' operation is overwritten and the only C++ 'new' construction is performed in creating the world itself).
