NOTES:
1.0.3 - Taken out all "add stand from external" functions as
we're going to make a "cart" style widget for organisers to use on their sites
1.0.3 - Added function open_contact_window(email). First seen in EOW2009
1.0.4 - Added forename and surname fields for Save/Retrieve. Fields added to DB also.
1.0.4 - Save/Retrieve validation added
1.0.5 - Clear fields once email is sent to colleague
1.0.7 - Started a refinement of duplicate element mirroring. Finish
      - Finish this refinement and we might make 1.1...?
