rainbow-dark: more aggressive darkening

- Body text color bumped from %w (light grey, sometimes renders ~white)
  to %K (dark grey / 'bright black'), affecting msgnick and all action
  templates.
- Statusbar / info bg changed from %8 (terminal default, which some
  terminals render as reverse-video white) to explicit %0 (black) so
  the bar is reliably dark everywhere.
- Added color to spots that were falling through to terminal default:
  whois values, servernotice body, wallop_nick, wallop_action body,
  dccfile.
- Expanded 'fe-common/core' formats block to override joins, parts,
  quits, kicks, nick/topic/mode changes, aways etc. — coloured nicks
  via the existing abstracts but the surrounding 'has joined' /
  'changed the topic' verbiage now renders in dim grey instead of
  stark white.
