The Return key should navigate to the next login-form field

[AngeloStavrow]

Testing this on my iPad, tapping the Tab button navigates through the form fields, and pressing Return hides the keyboard (presumably because it doesn't have a default action).

Using the Return key to navigate between fields in e.g. Contacts or Mail seems to work the same on both iPhone and iPad, so the task at hand seems to be "make the Return key's default action to navigate to the next field."
