Pagination and Auto Updating

This release adds pagination to the shipdb display. I ran into a bug that I couldn't quite crack when the shipdb list ballooned over several hundred records. The click filters stopped working. I could not pin it down and I suspect it was related to the sheer amount of lines being rendered. Regardless, it is better practice to paginate these results for a table that could be theoretically infinite in size just for the sake of resource management.

I've also added a function that will check for updates and can manually be run from the alias command to check. It'll prompt the user before doing so and reference the release page for the latest version.
