fixed url of stepnav when using base-element in html
depage-forms: small enhancements

- added exception when validator is not callable
- made valid public
Bug Fixes
Added Validator->isValid Method
Added uploaded to global.js

Added an initialization for the depage uploader in the global.js file
Added Autosave Validation

Added a function for validating autosaved elements by checking for the
'formAutosave' flag and then validating the corresponding elements in
the post array. Need to check this is correct implementation.
depage-forms: added a fix for taps on labels for checkboxes and radio buttons for iPhone/iPad
Autosave Fix

Autosave checks if there is data in the POST array before attempting to
validate

Fix CRLF
removed general uploader because the php/javascript are not inside the htmlform 

this means that one will have to add the uploader in the specific project.
depage-forms: added class for skin in lists
Added checks to prevent warnings
Improved 'formAutosave' checking

Added a (boolean) check for formAutosave in the process method, to
prevent redirecting ajax calls.
depage-forms: simplified validateAutosave
depage-forms: added get text-localized error-messages for inputs
Fixed issue with select-multiple not sending array of values

jquery sends all selected options as an array
Added setupForm() method. Moved code from document.ready() call.

This allows forms to be initialized after an ajax request is made.
