Add a new --cabal-lib-version flag to the install command It's used to select which version of the Cabal lib to use when configuring, building and installing packages. It's mainly so that we can use cabal-install to help us test that packages build ok with both old and new versions of the Cabal library. In particular we'd like to check every package on hackage to make sure that new Cabal versions are not breaking packages that worked with older versions.
