Over the board feats: Resign, Offer Draw and notification on threefold repetition

[andy-ife]

This pr adds three new features to over the board games: resign, offer draw, and a notification on threefold repetition. No new widget or class was added, and these features were implemented much like they are in regular online games.

Fixes #1029

Changes made:

• OverTheBoardGame model class: Added three new getters: abortable, resignable and drawable. Calculated the same way as in the Game model class.
• OverTheBoardGameController: Added two new functions: resign() and draw(). Also added a check for a threefold repetition on every move.
• OverTheBoardScreen: Added a hamburger menu to the UI, added listeners for the new controller functions, and used YesNoDialog to request user confirmations.

Tests performed:

• Ran flutter test. Some tests failed, but these were not due to any changes I made
• Ran flutter analyze. No issues
• Manually tested the new features - debug build on an Android device, API Level 31
