Fixes rummy reset functionality and removes What did you say from games (except rummy tutorial).

Notes:

1. There is a standing new bug caused by other core system parts, which is not a result of this pull request. >>>Update: Resolved and sync'ed

2. This changes AdjacencyPairBase and adds a small flag which by default has a value that does not affect the functionality of other plugins. You can set it to false to turn off what did you say button.

3. As a result of merging this, VS should be built again.

4. Fixes the bug that user could play two moves in a row in one turn very fast for both TTT and Checkers!

5. Improves locking in checkers, small timing improvements, cleanups, etc.

Thanks, 
Yours,
