Evite to Google Calendar Greasemonkey Script v1.3 

I'd noticed a couple of problems with my Evite to Google Calendar script, so when I got an Evite today, I took some time to figure out how to fix it. I fixed everything I could find, and made the script a bit more robust at handling future Evite changes. So, if you've been having problems, give it another shot and hopefully it'll work for you now.
