common code from all activities to one BaseActivity
call setTheme before super() on all activities onCreate()
Improve the background color of the selected tab in all dialogs.
Convert TransparentButton to Material Design.
Correct the style.
Convert the theme to be a MaterialTheme and the TransparentImageButton to be a MaterialButton - the first forced by the second, and the second because a MaterialButton gives us control over the location of the icon in top of it. We need that because of the new 'solve/scramble' split-button in the lower right of the Play screen.
New RubikSettings dialog.
New module: Rubik App. Initial commit.
