Initial support for mobile devices (#787)

* Initial support for mobile devices

No editing yet, but UI looks nice and you can open the canvas menu

* Add support for editing shape color, etc

* Allow the mobile menus to cover the shape selector

* Hopefully fix test error

* Fix touch on canvas

* Fix safe area handling & remove unused Island
