Previously everything lived in an inner class method of
SettingsRobolectricTestRunner. That method has now been turned into
a static method so that it can be called by other runners.

Reworked the way screensaver settings are laid out for O. Instead of
using the options menu and dialogs to navigate screensaver options,
there are now two rows: one row for the screensaver choice and
optionally its own settings, and one row for the "when to show" setting.
And now there's a nice obvious button you can press to preview your
choices.
