cmake

Ok, maybe using premake was not my best idea and it's better to use tools that everyone else know. So let's try cmake. This is an initial iteration that supports only Linux for now. Second step will be adding OS X support because it's much more similar to Linux that Windows but first of all we need to get OS X version running again.

To build from command line just run:
    
    cmake -G "Unix Makefiles" . && make

or use IDE that supports cmake natively like QtCreator.
Feel free to test it and express any thoughts and comments.
