Stuck-check logic

[hajo4]

I'm using PySol 3.4.1, and the game still produces "no more moves"-messages, when the game is clearly not stuck.

Here is an example for Flamboyant:
Flamboyant-37500088040934891520_stuck-bug.zip

Open that game, get Hint. Or start Assist/Demo to see that the game is considered stuck.
To win, just drop the red king from the last face-down cards.

Same bug happens, eg. in Freecell, when some cells are free.
