Change Layout Option for Android App

[LearningAsIGo71]

As was suggested for web layout in issue #108, I would like to see a tile/grid type display implementation for the Android app much like how some launchers allow users to custom configure the amount of rows and columns for the Android home screen and/or app drawers. On my P7 phone I would prefer something like a 3 x 5 grid, but if I was using a tablet I would probably opt for 6 x 8.

In the Ente Auth settings an "Appearance" category could be added and the Theme category moved into it along with a "Code Display" category which would allow users to choose between List (as it currently is) and Grid.

With grid tiles there likely wouldn't be enough room for the "Next" code display, but I personally would be fine with that. Or you could add an option to long press a tile to display the Next code.

Keep up the excellent work! I am very grateful for this app and to finally get away from awful Authy!
