Ditch the roster registration sheet

[phultquist]

I wrote so much code on the roster registration sheet, but it all sucks. here is one, and you can see it is made to look nice.

But, in return, it is terribly complicated.

The only valuable code here is what puts results into a PowerPoint. That's in slidesMerge.gs. If all the results were in Airtable, instead of this horrific spreadsheet, we could figure out the top scorers very easily.
