patch applied (cabal-install): Add ConfigExFlags and related command

[Duncan Coutts]

  * Add ConfigExFlags and related command
  This is for configure flags that we use in the configure command in the
  cabal command line tool that are not present in runghc Setup configure
  command line interface. These are flags that we are moving from the
  install command, so that we can also use them for the configure command.
  Initially it's just the flags for specifying package version preferences
  and  the cabal library version. We'll add constraints later.

    M ./Distribution/Client/Config.hs +13
    M ./Distribution/Client/Setup.hs +64
