Switch CaptivePortalLogin app to use theme like Settings UI.

The theme is switched to Theme.Material.Settings.  The progress bar
window feature is not supported in Material (b/16652978) so I added
a progress bar to the layout.  The Theme.Material.Setting's accent
color is set such that ProgressBars are indistinguishable, so accent
color is reset back to the parent's setting.
