Added Meshes and Animations (And many more)

Added NzTexture::IsMipmappingSupported
Color::(FromTo)HSV now takes hue and saturation in degrees
Fixed Context::EnsureContext
Fixed COW thread-safety (String, Image, Matrix4)
Fixed Quatenion<T>::operator*(const Vector3<T>&)
Fixed ResourceLoader
Fixed String::Resize with a size of 0
Fixed Texture mipmapping crash
Fixed per-class thread-safety
IndexBuffer and VertexBuffer are now resources
It is now possible to use more than 8 texcoords per shader
Moved all enumerations into separate files (Core/Enums.hpp,
Utility/Enums.hpp, ..)
Removed NzContextParameters::defaultWindow
VertexDeclaration has been rewritten (New interface/COW)
