  * Put the haddock and hscolour version numbers in the global ProgramConfiguration
  We do this during the configure step and then later we don't have to run
  haddock & hscolour again to find out their version numbers.
  This also eliminates some annoying module interdependencies.
  Eventually the Program abstraction ought to include the ability for programs
  to discover their own version numbers so it can be done more modularly.
