Sign Up List Updated

I made some changes to the sign up list today and the most important difference is that I fixed a bug causing people to accidently sign up twice for the same slot. When this happened it screwed up how my code displayed the list. If you notice any new bugs, let me know right away.

The other new feature is that it displays additional information about the event location (so far, the event has always been the Tree House’s open mic, but I made it so it can be used for any sign up list).
