Maze doesn't resume the game state if we close it with "Escape" key

[humitos]

Steps to reproduce it:

1. Open Maze activity
2. Click on Harder level some times
3. Press "Escape"
4. Re-open it again resuming it (without pressing Alt key)

Result:

• The level is an easy level

Expected result:

• The level should be resumed. Maze should start with the same level at the Escape key pressed time

The escape key should be removed/blocked, escape should not Stop the activity (this is an old pygame leftover I think). Ctrl-Q is the default shortcut in Sugar, and/or use of the Stop icon in the toolbar.

Ok, thanks gary. I will take this in mind when I'll work on this ticket.
