Source file extension changes (cc to cpp)

[abs1nth]

ok i commited my fixes now, if there are any problems just revert them and tell me to find another way ;-) i'm especially not sure about the type changes in shader.h but without them i get 50+ errors in shader.cpp...

it compiles now again but when trying to run i get this...any ideas?

Code:
