Android hardware button quit widgetbook application

[Martin Jablečník]

Description
When I run Widgetbook in mobile device, I have a bottom panel with 3 icons (Navigation, Addons, Knobs).
When I click on one icon so modal popup is showed with content. For close this modal you can swipe it down or click outside.
But when you accidentally click on Hardware button in Android, whole application is closed.

Steps To Reproduce

1. Start Widgetbook in Android mobile
2. Click on Addons icon in bottom panel
3. Click on hardware android button
4. Whole application is closed

Expected Behavior
When is opened modal popup, close this popup.
When is not opened modal popup, show dialog with question if I really want to quit whole application.
