Adding schedulers. Allows you to launch totems automatically

/totem scheduler » Show scheduler commands (ztotem.scheduler)
/totem scheduler list » Show scheduler list (ztotem.scheduler)
/totem scheduler remove <uuid> » Remove a scheduler (ztotem.scheduler)
/totem scheduler add <delay/repeat> <totem name> <day/minute> [<hour>] [<minute>] » Add scheduler (ztotem.scheduler)
Example: /totem scheduler add repeat myTotem 120 » Totem myTotem will appear every two hours
Example 2: /totem scheduler add delay myTotem monday 15 30 » Totem myTotem will appear every Monday at 3.30 p.m.
