[hge] Big pile of changesets...

[Ryan C. Gordon]

A whole bunch of really good work from Harley Laue just hit the 
Mercurial repo today.

For those that have been asking "how do I build this on Linux?" ...now 
you can, with CMake. Historically, I've been dropping the HGE source 
code into existing games, but this will let you build the engine and its 
tools directly.

He's done a bunch of other good work, which is also in the repo. Thanks, 
Harley!
