UINavCollection
This release adds the UINavCollection class to the plugin. This class essentially fixes the problem that UINavWidgets can't be nested.
Some fixes:
- Improve mouse input workaround binding (only bind when necessary)
- Fix CurrentInputType value from UINavPC when OnInputChanged is called
- Use TheSelector only if enabled
- Add GetButtonFromGrid2DCoordinates functions
- Improve selector changing direction halfway through navigating
