Change <a> tags to <span> tags to prevent page change in angular

This doesn't really make Firechat 100% compatible with Angular but it does bring it a good deal closer.

To see the effect I'm trying to get rid of you can just include the angular library in any page with Firechat, all the buttons will cause routing. There doesn't seem to be a good way of avoiding that without changing the tags.
Hrm. I think these should actually be buttons, since they are serving the role of buttons. Span doesn't strike me as the right answer here.
