Generate new content in New Header wizard for JQM 1.4

The automatical enhancement of links in toolbars as buttons with inline and mini style, as well as positioning the first two buttons in a header left and right, is deprecated in JQM 1.4 and will be removed in JQM 1.5.
In JQM 1.4, buttons should be set with classes, i.e. positioning is set by 'ui-btn-left' and 'ui-btn-right'.
For JQM 1.4 wizard should generate code

<div data-role="header">
    <a href="#" class="ui-btn-left ui-btn ui-btn-inline ui-mini ui-corner-all ui-btn-icon-left ui-icon-delete">Cancel</a>
<h1>My App</h1>
    <a href="#" class="ui-btn-right ui-btn ui-btn-inline ui-mini ui-corner-all ui-icon-check">Save</a>
</div>

Input controls of wizards in both versions can be the same
