Fixed the crash that would occur when the Refresh button was pressed in the controllers config.

- Simplified the locking mechanism when controllers were updated
- Reloaded the config of the controls instead of re-initialising the control plugins
- Fixed controls being unresponsive after the Refresh button was pressed
- Disables the hotkeys while the controller config is open
