Update parent inventory folder version numbers when folders are moved/created/deleted to match version numbers cached by viewers.

Browse Source 
This is done in the way that one would expect (e.g. moving a folder increments version number on both source and destination parent folders).
This should hopefully improve viewer reuse of its cached inventory information.
Currently MySQL only but will be implement for SQLite/MSSQL if there are no issues.
