Fix delete on right key on update_connection()
Looks better with tactile-highlight-bg
Made register/login forms horizontal
Add "wizard" for adding the first connection after register
Redirect to server log after adding a connection

  - Add welcome message unless server log contains any messages
  - Will only change user:$login:conversations from irc events
  - Change redirect_last() to redirect to (random) server log unless
    any conversations
  - Change redirect_last() to redirect to wizard unless any connections
    are defined
