Make user emails non case-sensitive

[brideylea]

Is there a way to make the Workspace ignore case for user emails/would this cause any issues? I've been having some difficulties with users added twice to the workspace but with different capitalisation in their email address e.g. s.morey@latrobe.edu.au vs S.Morey@latrobe.edu.au; or people trying to add a user to an item as e.g. bridey.lea@gmail.com would not work if I had been added as a user under Bridey.Lea@gmail.com.
