Add i18n support to the User Editor / registration interface

Per LP # 754898, the Register Patron interface currently contains
many hardcoded strings. Given that the previous patron registration
interface supported translation, this is a regression in 2.0.

Accordingly, we extend the use of Dojo i18n support to provide the
strings for buttons and a number of labels on the Register Patron
interface. The bulk of the remaining text is provided by the fieldmapper
definitions, which should in theory be translated automatically for us.
