Tournament changes

This is basically just a bunch of fixes for problems noted last time the new tours system was used in the main channel.
Them being:
/commands and /rules only showing the tournament versions (now you need to type /commands tournaments (or /help) and /rules tournaments (or /tourrules)
Messages showing up twice in the main chat, since it tried sending to the main channel and the tours channel, and them being the same thing made it double up.

I also fixes megauser commands not working for the old system (this was done on the main PO repo already, but I'm guessing this is slightly outdated).
The new tours sytems commands/rules can now be viewed in any channel that doesn't have the old tour system in place via /commands tournaments and /rules tournaments

And lastly just fixed up tournaments.js using tabs instead of spaces and fixed a syntax error left behind :x.

Majority of this is only useful if the new tours system is being used in Main Channel again, if not well most of this doesn't have too much of a point :x But I believe Zero preferred the new system.
