Bounds are not updated correctly for manual meshes

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create mesh/submesh at runtime, esp. using clone()
2. display bounds in Ogre
3. bounds are incorrect

Patch adds 2 manual methods to update bounds manually.

By the way I forgot to mention it also seems there's no way to sync up the 
gkMesh bounds to the Ogre mesh bounds after the mesh has been loaded, this is 
because the _setBounds method is only called once when the resource is loaded 
under gkMeshLoader::loadResource()
