Enables Field fields and extra fields in a bundle to be added to the addressfield widget. It will look like one widget, but they're separate fields. You can add any kind of field, so you can extend the addressfield widget however you like.
Trim strips all leading and trailing whitespace from all fields in all form submissions.
The module trims prior to validation, so for instance if you have an integer field and a person entering data fat-fingers a space after a number, he gets a successfully saved node rather than an error message about invalid input.
