added a jQuery api viewer demo. NOTE: content is a modified version of the downloadable HTML from http://jqapi.com 2010-09-16 17:13:38 +00:00			`<!DOCTYPE html>`

Added viewport meta elements to the markup of every template and removed the metaViewportContent option from code and docs. IE does not support generated viewport tags. 2011-02-18 20:00:18 +00:00			`<meta charset="utf-8">`

Big update: 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. fixes issue 32 2010-09-18 16:20:35 +00:00			`<div data-role="page">`
updated markup to use data-role attrs in place of classes for header/content/footer 2010-09-21 14:58:54 +00:00			`<div data-role="header">`

switched up padding and margins on content div. Now it will get 15px padding, unless its a fullscreen page. Inset listviews have no margin now, and regular listviews have -15px margins. Also, collapsibles now have no padding. Updated HTML to remove ui-body classes for content divs, to match these changes.
