Improved /g && /a

Was a bit confusing how it was all put together so I made it how I think it should be. Don't merge if you don't want it like this.

/a will send a message to the administrators. The administrators can also talk amongst themselves using this. (Only visible by other administrators) Has a red + before the text.

/g will send a message to the guardians and the administrators. The staff can then talk amongst themselves using this. (Only visibly by guardians and admins) Has a blue + before the text.

This will allow staff (and admins separately if they so want) to communicate without use of channels etc.
