v1.1.1: Xbox controller support, first update since release

Hello! This is just a quick announcement that I've updated my PuzzleScript fork - and in turn, this game - to include the vanilla PuzzleScript features that have been added in the last 5 months, which notably includes support for Xbox controllers.

Nearly all of the work is from increpare and some other PuzzleScript contributors (a.k.a. not me), but I still thought I should announce the update here since it happened after the game was released to the public. (Yes, the game says it was published in November, before the 1.0.1 to 1.1.0 updates, but I left it unlisted until January 8.)

I suppose I did technically do a bit of coding for this update by fixing a bug with gamepad controls, though (and made a pull request to get the fix added to vanilla PuzzleScript, though it hasn't been merged or closed yet) - it's literally just 2 lines of changes (but duplicated between 2 files for reasons), but it is something, and you can thank me for being able to move down with the joystick without also toggling grab.
