Added space bar name to InputManager
Removed `iniparser` from `deps`.

I will now use a configuration library available on most distros
(called libconfuse), so to not distribute my package along with
others.

I may, however, make a separate branch with libconfuse attached
to make it easier for small environments (like Raspberry Pi).
Trying to fix an error several people are having, about unrecognized c++0x flag
