Display UI immediately ASAP, load data asychronously about matterhorn HOT 3 CLOSED

Does brick or vty have a notion of off screen rendering? In graphical libraries you can take your time rendering to an off screen buffer and then when it's ready switch the display to use that buffer. It might be nice to prepare things off screen and then make it active once it's fully loaded. Otherwise, I guess the "Loading..." indicator could be displayed on top of the other widgets.

Current status: much faster than it was before, but we still load some things (channel list, user list, messages in town-square) synchonously. That said, I'm going to leave this issue open, because I think we should probably go further towards making the UI load up.

Okay, at this point we load chat channels asynchronously on startup and DM channels on-demand, which goes a long way to making this faster. It still takes a half-second, but I think we can consider this closed, unless we want to have the UI pop up immediately before any data has been fetched, which I generally don't think is necessary—the half-second pause seems perfectly okay to me.
