Mapbase v4.2

- Added keyvalue to use random bounds on logic_timer to limit AddToTimer/SubtractFromTimer inputs (suggested by White_Red_Dragons)
- Fixed inconsistent env_projectedtexture state on save/load
- Added code to allow skybox to use a direct entity handle instead of a stored origin and angles in order to take advantage of entity interpolation while moving (less jittering)
- Moved map-specific file manifest parsing to happen after other entities are created (highly experimental)
- Added various misc. code improvements related to debug build and MP branch
- Fixed some VScript ammo type-related code forgotten in the previous update
- Added more VScript functions to CBaseAnimating, including pose parameter functions and the ability to look up bones and get bone position
- Added more origin and angles functions for VScript (suggested by krassell)
