  * Auto-reconfiguration when .cabal is newer than setup-config
  
  This patch adds "ConfigFlags" to the "LocalBuildInfo" and reuses them to
  perform "configureAction" when .cabal file is changed. This has
  the same effect as re-running "configure" with the most recent used
  set of options, which should be the sensible thing to do.
  
  Closes #294, #477, #309 and #518.
