BUG: My Account: Can't change my email address

[wanderslth]

Having just gone through the pain of changing over all our email addresses from @gp to @flex, just noticed that we have no notion of letting a user change their email address:

1. Go to My Account
2. Go to Profile
3. Email is grayed out.

Any technical reason why we don't allow this? Should we offer this, some considerations:

• People will need to re-verify
• Probably smart to send a confirmation/notice email to the previous email as a security measure
• Need to realize this will populate for other teams as well as billing, etc.
