* Collection of random insignificant changes.

- Added progress indication on map-server shutdown when objects are removed from maps, as it takes significant amount of time to complete.
- Moved ers_free in db_obj_vclear, so that the node pointer is not used for comparison after it has been freed.
- Some documentation of shop packets.
