Venue Support in Event Info

- Added event venue support. If the event has a venue address, display it. If not, display just the location like before.
- Added json null check to website in event deserializer.
- Edited 'no data' string in event @ team to explicitly say no alliance or
record data

Originally, I had the "at" in the venue container just like the event location, but it looked a little off, so I took it out.

You might get a SQL column error case since I added venues to the database; a data clear/reset in settings should do the trick. Hopefully, I didn't break anything... (not very familiar with databases)
You forgot to update the cursor indexes below
