Sparemint Updater GEM UI Code

I managed to pry myself away from Anarchy Online tonight to work on GEM. I've been getting somewhat obsessed with this online game which is probably a bad thing ;) Anyway, tonight I did 99% of the code for updating via the GUI interface. This puts the sparemint updater ready for a 0.1 release, and it'll make it functional and ready to switch the dev website to live. Pretty cool.
