version 2.0

• Updated the Lua interface, breaking compatibility with existing scripts:
  • It is now possible to open multiple devices simultaneously
  • You can add macrodevice.open(backend, settings, input_handler) to the bottom of your script to restore compatibility
• Changed the way root permissions are dropped
  • Removed the --user and --group options
  • Use macrodevice.drop_root(user_id, group_id) or macrodevice.drop_root("username") in your script instead (after calling macrodevice.open(…))
