untracked files on master: f68de1e Revision: Undo unsafe change to TLuaInterpreter::clearRoomUserData()
BugFix: unable to remove room user data item if key had spaces at either end

Also restructured error messages for recently added/changed lua commands:
clearRoomUserData(), clearRoomUserDataItem(), getRoomUserData(),
setRoomUserData(), getRoomUserDataKeys(), getAllRoomUserData().
to follow recommendations.

Removed unused code remnant from earlier version of clearRoomUserData().
