Fixed many bugs

Added NzOpenGL::GetEntry
Activated preprocessor error if not compiling with a C++11 compliant
compiler
Cube can now be constructed with a Rect
Desactived utility option "threaded window" (bugged)
Epured Image interface (No more UpdateFace, use Update with z = the face
you are targetting)
Fixed compilation errors (Thanks to RafBill)
Fixed predefined colors not exported
Fixed uplading pixels not aligned by 4 bytes
Fixed Thumbs.db files not ignored by git
NzImage now supports Filling and Flipping (Horizontally and vertically)
NzImage::Get(Const)Pixels now support pixel location
NzVector(2/3) can now return floatting distance/length with all types
NzVector(2/3/4) can now be constructed by a vector of smaller dimension
Premake now set "-std=c++11" build option for GCC
Renamed NzImage::(Get/Set)Pixel to (Get/Set)PixelColor
Updated new([])/delete([]) in the leaks tracker to the new C++11
signatures
