Multiple Bugfixes (0.22.2 Alpha)

This update brings a number of bug fixes related to how window settings are stored from one run of the game to the next.  It should take care of that pesky bug I've seen where the window kept appearing on the wrong screen under Linux.

The biggest change is that saved settings related to positioning the window will be checked before they're used.  So, for example, if a user copies the game's directory to a new computer and the graphics setup is different, defaults will be used.  The same goes for the user changing their desktop resolution.
