Big skeletal animation update

Added MeshInfos demo
Added MD5Mesh/MD5Anim loader support
Added Node class
Fixed ResourceParams not being exported
Added support for skeletal animation
(Animation/Mesh/Joint/SkeletalMesh/Skeleton)
Meshes are now only stored with VertexStruct_XYZ_Normal_UV_Tangent type
Moved Sequence declaration to Sequence.hpp

-Animation:
Renamed Create to Create[Keyframe|Skeletal]

-AxisAlignedBox:
Added Contains method
Added GetCorner method
Added GetCube method
Added Transform method

-Cube/Rect:
Added GetPosition method
Added GetSize method
(Almost) Fixed ExtendTo method
Fixed GetCenter method

-File:
Added GetDirectory static function
Added GetPath method
Renamed GetDirectoryPath method to GetDirectory

-Math module:
Fixed constructor/methods taking a non-const array
GetNormal/Normalize methods now takes an optionnal integer pointer
(returning length)
Made all classes default constructor trivial
Inverse, MakeIdentity, MakeZero, Normalize, Set methods now returns
reference to object

-Matrix4:
Modified methods to avoid copies
Removed COW (Too much overhead)
Removed Concatenate[Affine] static function

-Mesh:
Renamed Create to Create[Keyframe|Skeletal|Static]
Renamed Skin to Material

-MeshParams:
No longer takes declaration argument
Renamed loadAnimations to animated
Storage default to BufferStorage_Hardware if supported and
BufferStorage_Software otherwise

-OpenGL:
Added glGetBooleanv function
Added glIsEnabled function

-Quaternion:
Added ComputeW method
Added Conjugate method

-Renderer:
Added IsEnabled static function
Fixed GetLineWidth function not being static
Removed SetVertexDeclaration

-RenderWindow:
Made CopyTo[Image|Texture] method constant

-Resource
Fixed RemoveResourceListener crash

-ResourceLoader:
Loaders are now used in a LIFO context

-Stream:
Renamed GetLine method to ReadLine

-String:
Fixed Simplified

-Utility module
Added configuration define for strict resource parsing

-VertexBuffer
Now takes a VertexDeclaration pointer

-VertexDeclaration
No longer throw an error when getting a non-existing element
