Preference saving, UX sucks less

After using this tool for another week since it went public I got kinda tired of entering the same names of the same friends and checking the boxes the way i did last time.

No more! Now whenever you re-roll roles it saves names and preferences to your computer locally. Next time you load this page it will set all of the info to how it was and automatically re-roll.

You could also call this a UX improvement since the amount of work returning players need to do when they load the page just went from entering 3 names & clicking a few times to literally zero.
