Reorganization of code

[Zardoz89]

I'm going to structure a bit better like this:

/cmake         <--- Cmake modules
/assets        <--- Image files and similar stuff
/src           <--- Here all .c , .cpp  and .inc files
/src/devices   <--- Here all hardware devices
/src/audio     <--- Here will be placed all code that handles audio 
/include       <--- Here all .h and .hpp files. Mimics /src/... structure
/include/devices
/include/audio
