[Bug/Request] ChatEditBox

[Brainn]

The ChatEditBox is somewhat inconsisten when using multiple chatframes. I have 2 chatframes in my interface, and about 90% of the time the ChatEditBox attaches to the second chatframe, but sometimes it attaches to the first chatframe. I cant find any pattern why this happens.

A option to mark a chatframe as the 'primary target' for the chateditbox would be a good adition.
