Code Releases Activity

Added dialog displaying device ID and QRCode addressing #790 (#912)

Browse source 
* Wip adding dialog.

* Wip adding ImageRequest functionality.

* Got a text converted to a QrCode using the syncthing Api.

* Dialog now shows device ID and QRCode.
The dialog also keeps it state when the device rotates and the copy ID functionality has been moved
to the dialog, from the drawer.

* Moved share device ID functionality to the Device ID dialog.

* Addressed code change requests and added improved dialog layout by @nutomic.
