Nice-to-have: Automated stress-testing (low priority)

[davidjoffe]

Would be nice to be able to automate certain core actions to help stress-test the game and engine, e.g. mainly:

• Game exit (so a script could repeatedly run it, run some stress-tests, close it, repeat for hours)
• Starting and running game
• Incrementing levels
• Exit game
• Things like currently-beta in-game fullscreen switching, e.g. run it hundreds or thousands of times
  This could help make sure the code is robust and cleaning up where/when it should be etc.
  But it's far from necessary at this point.
  Some of the code may overlap with the idea of possibly doing recording/playback of games.

A command line option could possibly enable stresstests e.g. then a shell script could have a simple loop of e.g.:
"./davegnukem --stresstest"
and/or "./davegnukem --stresstest -f"
so it could sit in a loop running the game, letting it load and auto-increment levels, stresstest things like fullscreen toggle, cleanup.
