- make undirected infos and errors temporary (and static on 'status')
- make irc erros in backend directed
- fix cfg:server stuff on client connect (remove it and replace by local help)
- make /presence command (for IRC it toggles just away status)

- add tcp keep alive to Net::IRC3?

- improve irc mode setting and general any channel actions
  - make irc invites being displayed etc.
- add XMPP support with Net::XMPP2 (which still isn't released)
- add authorisation to backend (digest md5 auth of some kind?)
- allow correct display of multi-line messages

future:
- implement formatted messages (for wrap-padding and colors)
