By popular demand (well, one user so far), I've added rudimentary support for window state storage to RunSnakeRun.  There's lots more state that could be stored, but for now it just stores the window position, size and maximization.  Should be considered an alpha-level feature for now, as it is untested on Win32 or OSX.  If someone wants to hack in more state-storage, or test/fix on those platforms, feel free to branch and request a pull or send a patch.  Enjoy.
