Match Display Name: Duel vs General AND UF Upload

[Fredenck]

Currently we have two types of matches tagged:

1. Duel: UCLA vs another school, 6 singles, 3 doubles, ...
2. General Event: ITA Sectionals, Rudy vs xx, Spencer vs xxx. These are one-off individual tournaments that don't fall under the category of school vs school.

Proposal: add a checkbox in the upload-match for Duel. When this field is true display ; otherwise display on the Dashboard

• Additionally, you will need to update matchKey in Dashboard.js. This currently hashes matches by <date>#<opponent>; this must hash <date>#<Event> when the match is a general Event

The second part of this issue is adding a checkbox in upload-match for Unfinished. When this is False, process the set scores and make sure they are complete. If not, raise an error so the uploader doesn't mess up. When this is True, allow any set score combination.
