Some additional __doc__ comments (with some ideas for future plans) and removal of some unnecessary imports.

Clean up some deletions from previous rearranging that did not get committed.

Move soc.views.user.profile.profile() to soc.views.user.profile.edit().

Flesh out the user/roles placeholders a little bit more.

Created response helper respond() function that is used to generate base templates and it's child templates (handles sign in/out links, user name etc). Updated User model helper text. Added basic user profile view (not finished yet). Added css entries for buttons and added buttons background. Added /user/profile and /user/profile/linkname support in urls.py.
