[LuaCheia] build system

I would vote for the Lua based 'premake' as it can automate the various 
platform build-files (project files) etc. nicely.

parts. For one MinGW is very much closer to the *IX way of doing things, 
and it's free.
I'm not sure if we _need_ to support MSVC directly, as we are mainly 
trying to provide a binary distro for the various plattforms (?(
