Add option for showing today's scores alongside yesterday's during rollover period (PR available)

[dathbe]

I've tweaked the code to allow for the display of today's scores even during the rollover period. So you can see both yesterday's score and the upcoming game at the same time. For SNET, that required adding a new provider to check yesterday's scores from SNET, which polls once per hour (presumably, the scores from yesterday won't be changing much).

I can create a PR, but this repository doesn't seem to be active, so I'll only do it if requested.
