+- SubMesh class now has a OnSubMeshInvalidateAABB signal, triggered when a new AABB is set to the submesh
+- Mesh class now has a OnMeshInvalidateAABB signal, triggered when a mesh invalidates its AABB, which is also submesh updates its AABB
+- Model now invalidate properly their bounding volume when their mesh AABB is updated
+- Added operator&/|/^ taking an enumeration value and a Flags object using the same enumeration type.
