Once off scoresheet upload

[Joshua]

It might be nice if you could press a key at the score window to upload your scoresheet even if uploads are turned off by default.

Rationale: I turn off score uploads when I am doing something lame like farming the same seed over and over (eg to get certain rare unique items or encounters), and often forget to turn them back on after those runs until I get to the end game screen and find out it wasn't uploaded. Also I think at least one player keeps it turned off until he is about to win, then turns it on.

Yeah I can see this having its advantages--it's been brought up several times over the years, but it further complicates the end game screen so it's not something I've wanted to implement so far. There could be a better alternative way to handle this that I've considered doing, but we're not there yet.
