Changes:

• Support for firmware 12.1.0.
  • Firmware 12.1.0 updated the home menu, it's recommended to uninstall the currently installed themes, extract the home menu (you should be automatically prompted to do so) and install them again from the original nxtheme files.
• New command line options to diff and extract szs files in the theme injector.

Edit: The theme injector zip has been updated to remove the dev version warning. No other change was made
