Redesign user profile page

[andrewhavens]

Design for editing your own profile as well as a public profile that someone could view.

Public information that should be displayed on a user profile page:

• Display name
• Profile Photo
• Grid of skill level matched with role/area of expertise (developer/designer). See Allow users to assign roles to themselves. #30

I should be able to edit these settings on my profile (but they aren't displayed publicly).

• Email
• Password
• Email Digest Subscriber
• Email Frequency
• (Remove "Displayed welcome message" checkbox)
