New description:

 As in #168

 if I have foo-1.0 installed, and foo-2.0 is available, "cabal install foo"
 should upgrade foo to version 2.0

  1. If the user specifies a package without a version, and a newer version
 is available on Hackage, that newer version should be installed.
  2. If the system is installing dependencies on "foo", if the dependency
 can be satisfied locally, do not install the "hackage" version, even if
 it's newer.
  1. If a user specifies a specific version
    1. if that version is available locally, use that
  1. if a user specifies a version range
    1. if that version can be satisfied locally, but not from hackage, use
 the local version
    1. if a newer version on Hackage satisfies the dependency too, install
 that.
