Update /help

[Ruairi]

Last time I was on here I noticed that the /help command didn't really show you everything you could do. There's LOTS of commands that seem to be missing from the list, which should probably be added.
Although that was like 3 months ago, and if the help command was updated then well...I look like an idiot.

Mostly stuff like Faction Tags and a few other misc. items, but still, we should have every command listed there so people (like me) don't go around bugging people with //OORP messages asking "WHAT COMMAND DOES THIS"

Of course the wiki probably has all the commands but like, that requires ALT TABBING, UGH!
