[scottjehl]

Footer and Header get ui-bar-[theme]

[scottjehl]

mobilize now:

• applies data-themes appropriately to header,footer,page,and content roles
• finds first link in header or footer, applies left button class
• finds second link in header or footer, applies right button class
• if no left button, a back button is auto added (this can be disabled through $.mobile.addBackBtn)
• back buttons will not auto-add on the first page visited.
• all headings h1-6 are given ui-title class for constent styling in header and footer
• buttons in ui-bar,ui-header,ui-footer now all have consistent sizing and styling
