Bug 997547 - [MMS]Text to email from Contact details

the pattern for email does not support international emails (see http://en.wikipedia.org/wiki/International_email)
I think the pattern should just be something like: `[^@]+@[^@\.]+\.[^@]+`

And actually I don't get it; I thought we agreed on having a secondary "target" property for this, keeping "number" like it was?
