Chat suggestions for Classic, and others

[Zilyana]

1. /LegionAlert command for Brig and Deputies to use for Legion Events. This would be in case players have their legion chat in a separate tab and not open.
2. /2 (Trade Chat) needs to be Global. This helps break up the spam in LFG.

Also removing the "Hide Gear" option would be nice. It's getting to a point where people are viewing your gear and making fun of you because of using low level gear due to crappy drops. Having a character's gear permanently visible also removes the "Elitist" mentality of checking your stats before being invited to a Legion or Instance group. I think that a character's gear should be viewable, other people can see it visually on character, so they should be able to inspect you.
