Rewritted ResourceLoader and moved it to core

Added creation constructor to NzImage Added member function functor Added option to build Nazara as one library (instead of many) Fixed some 2011 copyrights Made use of "using def = T" C++11 feature instead of some illigible typedefs Removed unused premake file
