Improved interaction with "Input" settings.

- paired devices have notifications that they are configured and require connection
- paired devices load the configuration when connected
- A notification appears when changing control configuration settings.
- Now control settings will be saved only when they are changed
- Added a button to roll back changes to the previously saved state
- Fixed a bug: when switching the "player", if the "input device" and "controller type" settings were changed, the save dialog box did not appear.
- "Motion", "Rumble" and "Led" also have events notifying about changes
