Refactor for havok 2012 1 0.

A few notes about this feature branch:

1. Also removed unused files.

2. Compressed mesh appears to be deprecated - not sure why that is, or how to migrate (I found no information about in the docs, but then maybe I also didn't look very hard).

3. Include and library path are absolute - probably we ought to have some convention so they can be specified relative to $(ProjectDir).

4. The size of the compiled executable is enormous - 8.6Mb (up from 143k for the old mopper) - do you know what's up with this?
