In several places, add support for specifying package.

This addresses:

- Issue #92: glide update [repo [repo [repo [...]]]]
- Issue #96: streamlines a bit from previous commits
- Issue #101: do not do redundant work on `glide get foo`
  - Extended that to do the same for `glide update`
- Set the foundation for #85 by adding package list to UpdateReferences.
  However, there's more work to do on #85, including some that will
  break backward compat.
