Simple Displays

A New version of Simple Displays intended for server operators only. Also contains minor text fixes of failing block display placement.

Compared to the regular version, in order to run commands you must be a server operator using /op. Secondly you must run /function simpledisplays:[command] in order to use commands. Commands are the same as /trigger but with the addition that they need "simpledisplays:" to start and remove all capitals.
