Unfulfilled Sign In / Register Feedback

(Note: Both of these issues initially appeared in bug #1608, Sign In / Register Feedback. That bug is mostly fixed, but these issues remain unaddressed. I'm filing them as a separate bug for reconsideration.)

1. On the "Thanks" page [shown to users after registering], above the "Now that you..." text, show the user's gravatar and username - and add a link to "View Profile" to drive people to that page and their API Key
2. Perhaps merge the Change Email Address page into the Edit Profile page, with the form hidden until you click the "change" link. Then the "Cancel" link would just hide the form again. The hard part will be managing state when the password is entered incorrectly.

Note: Item 2 is no longer applicable given the reworked profile page. I'll tweak up item 1
