Lots of changes again. Biggest ones:

- window's text buffer should work better
- themes are almost working, you can change the text formats with /format
- automatically try to rejoin the channel after 5 minutes if the join there
failed because it was "temporarily unavailable" (netsplits)
- generally cleaning code..
