expose lit mode interface in CKMesh.

- provide lit mode and wrap mode getter and setter in CKMesh.
- add lost flags setter in CKMesh.
- show lit mode and wrap mode data in Unvirt.
- add interface for lit mode in BMap, because some old Ballance map use lit mode to light objects.
- expose a raw c callback when creating bmap to allow user decide how the log output by themselves.
- change python bindings for BMap interface changes.
