fix build on linux

this commit mostly deals with problems caused by the fact linux is
case-sensitive, while windows is not, so some files were renamed to
match the pattern of the rest of the code and it also required a few
changes to some includes, to match these new names.

phonon includes (in Audio.h)  were also changed (I am not sure this will
work on windows, though)
