Rework UI code for multi-channel 

Tags are now permanently assigned (and I'm betting on never needing more
than 256 of them) and the UI maps tags to a linked list of views for
easy reordering and removal. Currently, views can only be added. Views
don't have a topic window until they need one. All UI code wants to be
functional reactive.

Beeping is temporarily removed until message priorities (status,
message, ping) can be added to the UI. At that point spawning
notify-send should also be possible. Priorities will also help with
unnecessary markers, which will not appear for status messages.

The tab system is now used to send QUIT and NICK messages to all the
relevant tags. Verbose output now goes to its own tag, and sending to
it sends raw IRC.

IRC colors are now listed in chat.h and handler functions for numeric
replies have real names. The color algorithm now uses a real hash
function for hopefully better results. QUIT, PART and KICK messages are
scanned for URLs.
