(alpha input) please lose mouse focus on keyboard/controller use

[Caelyn Sandel]

The current mouse input remains onscreen regardless of how long it’s been left alone.

Example repro:

1. Hover the mouse over an item in the Nearby Objects list
2. Use the controller or keyboard to walk around.
3. note that the context pop-up remains onscreen, obscuring the map.
4. Open an action menu and hover the mouse over an option.
5. Use the keyboard or controller to navigate the menu.
6. Note that the mouseover’d option remains highlighted.

Expected behavior:

When the user presses a button on the controller or keyboard, the mouse cursor is hidden and all hover actions are cleared

*Tooltips shown by mouse should now hide when keyboard or joystick buttons are pressed (please report any that do not as bugs)
