UI Enhancement - Add User Page

The Add User page flags an email address as invalid if there is a trailing space.  This can easily happen when users copy and paste emails addresses, for example, from a service request ticket.  Copying from web pages often results in a space being added to the front or the end of the text selection.  Please enhance the validation code so that it simply trims spaces from the start and end.  This might seem like a small enhancement, but when you're a large organization and creating batches of accounts, it can be frustrating.
