Extended Doxygen documentation of btKinematicCharacter

[Martin Felis]

Hi there,

I've been wrapping my head around the source btKinematicCharacter today and thought it would be sad to forget about everything. So I ended up adding quite a bit of comments to the code while removing also a few things that did not do anything. I tried to also extend the Doxygen documentation for this particular class, hoping other bullet users can benefit from it.

To make the changes public I created a github repository, located at https://github.com/martinfelis/bulletphysics2, if anyone is interested. It is based on the 2.79 release.

Cheers,
Martin

P.S.: Thank you very much for making this software available!
