Feature: Add "rematch" button to end of scoring page

[deiga]

I'd love to re-challenge my mates after a game has ended, but currently it's hard work going to the root URL (yeah, I can't even find a 'home' button) and then re-inputting the same settings everytime.

It'd be great if there were a "rematch" button, which would just exchange colors and otherwise use same settings.

I'm willing to look into it myself too, if you give me a hint on where to look :)

That's a good suggestion, thanks @deiga !

Honestly it's been so long since I've looked at this code base, I'm not even sure I know where to look anymore. I really want to get back to this someday...
