Title: Make bin/dot better by allowing it the ability to upgrade outdated packages.

You can upgrade individual packages, all of them at once, or none of them at all. It still does what dot used to do, but a little bit differently.

This is probably not the most efficient way to accomplish said task, but it is a start.
