FlipSight: Added Game Import from Tournament Diagram Sheets

I've added a new feature to FlipSight that lets you import games directly from tournament diagram sheets.

You can access it via:

FlipSight → Analyze
... (More) → Import → From Diagram

Due to the free usage limit for the number recognition feature:
* Guest users cannot use this feature.
* Logged-in users are limited to 100 imports per day.

I hope this will be especially useful for tournament organizers, participants, and associations that need to digitize games from printed tournament diagrams.
