Generate new content in New Footer wizard for JQM 1.4

1. Difference from JQM 1.3:
Buttons should be set with classes

<a href="#" class="ui-btn ui-btn-icon-right ui-icon-plus">Add</a>

2. Enhancement:
Already in JQM 1.3 controlgroup can be positioned left or right to the title by adding class 'ui-btn-left' or 'ui-btn-right' so that new input control can be added to the wizard

Bar position: o Default   o Left   o Right

enabled when input 'Arrangement' is set to 'Grouped'.
Default positioning is provided by flow layout, in which title and buttons are placed to different lines, which is implemented in wizard at present. For navbar, attempts to put it left or right result in poor layout.
