  * Rename --hscolour to --hyperlink-source and add haddock --css flag
  So now --hyperlink-source controles wether or not we run hscolour and
  get haddock to link to the sources. The new flag --hscolour-css can
  be used to override the css file that hscolour uses.
  Also, the new flag --css can override the css file that haddock uses.
