feature: Add mouse click support for moving between widgets (#208)

Adds mouse support to the application, to move between widgets and click on elements.

List of things to added:

- Click to move between widgets
- Click to move between widgets in basic mode
- Click on widget entries
- Ability to disable mouse if you don't like it, I guess
