integrating v1 mockups for user selected scopes

This pull request integrates the mockups created for user selected scopes. It does not contain the correct colors or logos. It does work with and without javascript so the javascript will need test coverage when we decide upon a js test framework. Designs can be found in #72 
the call to action here isn't really related to "scopes" ... the fact that we have a form to update profile data on the oauth authorization page and we have a rough mapping of scopes to profile fields is incidental. also, `enter` is not a great name ... maybe `prompt` ... so `profile.prompt.foo` instead of `scope.profile.enter.foo`?
