Feature request - profile fields on registration form

[enderandrew]

Problem: Lengthy registration forms dissuade people from signing up. However, moving extended profile fields to another group somewhat hides them. I've had users tell me they can't find where the profile fields are because they have to click to expose the additional profile field group when editing their profile. This isn't as intuitive as it could be.

Possible solutions: 1. Don't add the extended profile fields to the registration form so you don't have to move them to another group.

2. Add control over each field to show it on the registration form or not.
3. Show all groups when editing the profile.

I like suggestion 2 myself, though it'll take quite a bit of work to get to that point (especially for backward compatibility). Patches welcome!
