Prerender all buttons

[gtsop]

Jquery mobile parses the DOM to find all the elements with the attribue data-role in order to render them. Buttons are very easy to pre-render by writting all the appropriate classes jqm appends. For instance this element:

<a data-role="button" data-theme="b" data-mini="true" data-icon="gear"></a>

can be converted into this one:

<a class="ui-btn ui-btn-b ui-mini ui-btn-icon-right ui-icon-gear"></a>

which will decrease the time spent on rendering widgets and eventually the client's CPU load
