- New invisible walls system (for WOE SE and Battlegrounds).

- New script commands for this system "setwall" and "delwall"
- Added other scripts commands "changelook" (can be used to try clothes colors, hair styles, headgears, etc without saving this on logout).
- Added getmobdrops to request a list of drop and rate of an specified class.
