[Chandler-dev] Addressing fields should accept non-email addresses

[Katie Capps Parlante]

Yesterday in bug council, we noticed 3 separate bugs related to email 
addressing fields storing invalid values.

Grant has a domain model bug:
https://bugzilla.osafoundation.org/show_bug.cgi?id=5343

Reid has a detail view bug:
https://bugzilla.osafoundation.org/show_bug.cgi?id=7765

Bryan Stearns has a dashboard bug:
https://bugzilla.osafoundation.org/show_bug.cgi?id=7775

It looks like Bryan has a patch, but is waiting on Reid's task before he 
can check it in. Bryan, do you need anything more from the domain model? 
Should we close 5343 as a dup?

Cheers,
Katie
