The logic will actually support multi-option selects as well, but the labels are flipped in order for switch-style controls, so if we want to support regular sliders from selects, the labels will have to be in forward order and beneath the slider bar.
In starting markup, pages should now be identified with the attribute data-role="page". This allows us to then add ui-page programatically, hiding all non-active pages, and apply ui-page-active to one page at a time to show it.
mobile.js is updated to find pages by this attribute now, instead of ui-page class.
