Adds options to mass update profile fields directly from the user management page.
This release only support text and textarea fields. Checkbox, list selection
freeform list, URL, and date have not been implemented yet.
Also, I resorted to using a session variable to pass the callback arguments to the field update form. If anyone knows a more legit way to pass the arguments in the context of the hooks being used, please post it to the issues or submit a patch.
