Update mobile version to mobile v2.2.1

The android version just got a much needed update to fix some resolution issues on devices with cutouts.

It turns out the mobile source was actually pretty out of date, like 3 versions out of date! This commit brings it up to date.

All the changes have just been about keeping the game running on modern devices, though. The biggest change was adding the Starling library to the project, which made the game GPU powered and sped the whole thing up.
