  * Add a new module for handling user targets
  This will allow us to increase the range of targets that cabal
  commands can support. The new ones are local directory targets,
  local cabal files, local tarballs and remote tarballs by URL.
  Also a better way of doing the special "world" target.

    M ./Distribution/Client/Dependency/Types.hs +1
    A ./Distribution/Client/Targets.hs
    M ./cabal-install.cabal +1
