  * turn fancyPrinters into an IO action
  
  This is what it actually is, via getPolicy. The unsafePerformIO was
  perfunctory, since fancyPrinters (almost) always gets passed to a real IO
  action that does the actual printing. The only exceptions are when we use it
  for tracing and in the harness when converting our TestResult to HUnit or
  QuickCheck. Consequently showDoc has been renamed unsafeRenderStringColored
  (to discourage its use) and a function debugDoc added.

  * remove env var DARCS_DO_COLOR_LINES
  
  If the user wants colored output we should go all the way and not require
  them to set yet another configuration variable to achieve that. On the other
  hand, if they can't see colors or don't have actual colors in their terminal
  and thus set DARCS_ALTERNATIVE_COLOR then we should not color hunk lines
  since we have no alternative rendering for them.
