Fix/saving 2

The cookie is now a lot smaller.  Main thing is that there was a lot of information about triggers that I was saving (due to not knowing at the time how triggers were implemented, and perhaps some amount of laziness) that I don't think changes, and thus doesn't need to be saved.  I also removed certain variable names from the cookie to make it take up even less space.  It should be small enough now.

I did not change when it saves or fix problems with saving timed triggers in this branch, and the cookie still expires when you quit your browser (this can be changed).  (And remember that cookies don't work for file: URLs on Chrome.)
