Add "header" option

Default: none

Type: selector

what

If the option is set, the first matching element is moved from the dialog content to the dialog title bar.

If a header and a title are set the title option overrides the header option and the header is removed.

why

The title is a part of the content and should be defined with html markup.

When using html 5 a dialog can be defined as a section and the header cn be used as a title.

remarks

To keep the title small css rules like " .ui-dialog-titlebar > h1 {font-size: 1em;}" can be added to the css framework.
