Multi-WIP that I probably should have done in multiples commits:

- more colors settings:
  - server foreground
  - channel foreground (active, inactive)
- dumb cosmetic changes because why not (`!` -> `:(`, coloring)
- temporary lines to unclutter main ui from disconnections/reconnections
- display line head only once in case of multiple lines
- cosmetic motd
- handle 396 numeric as "server" head
- improved ACTION display
- imrpoved topic display

bugs:

- ACTION fucks up with multi-line head
- multi-line head needs rework before trying upstream
- what the fuck to with my cosmetic changes
- document new config values
