Found a little bug with the unlicensed games showing when they shouldn't have been, fixed some errors with game regions for some games, this may need the data clearing, or an uninstall and re-install.

Added a scroll view to the settings page as I discovered that it wasn't giving some users the option to export their game lists on smaller screen sizes.

Changed the main page to a constraint layout so that should make the buttons evenly spaced on the page.
