#758: expose existing functionality: fetchPackage/unpackPackage

---------------------------------+------------------------------------------
`cabal-install` has functionality for fetching and unpacking `cabal`
packages (`.tar.gz`, as produced by `cabal sdist`).
It would be very helpful to expose these functions as `cabal-install`
commands. `unpackPackage` is the more important of the two, though being
able to fetch individual packages from URLs (think blogs, wikis, ..)
without having to establish a full hackage-like repo would also be very
welcome.
Most importantly, you could remove the whole
http://www.haskell.org/haskellwiki/How_to_unpack_a_tar_file_in_windows
hazzle. Instead of package authors and users having to worry about whether
some unpacker is installed client-side, everyone could just rely on
