Added formats conversion

Functor, NonCopyable, Tuple are now parts of NazaraCore (NazaraCore no
longer needs NazaraUtility)
Added loadFormat image parameter (ask loader to load image in specific
format)
Fixed utility project building
It is now possible to convert, get validity or get name of pixel formats
Changed endianness macros' name
Removed useless NazaraEndianness macro
Removed unused files
