Allow form-based refreshes

[jmacdonald]

Currently, to refresh changes to form fields, all affected fields must have their individual refresh methods called:

$('#my_selectmenu').selectmenu('refresh');

Depending on the number of fields that have been affected, and especially because the various field types do not share a common method (selectmenu, checkbox, etc.), this makes refreshing complex forms very cumbersome.

Thanks for the suggestion. Since this is a feature request, I'm going to close this but we'll re-open when we decide to look into this in a future release. Mind link this up to the feature request wiki page? https://github.com/jquery/jquery-mobile/wiki/Feature-Requests
