Update the manage profile layout and styles

I got this ball rolling with some creative ideas from @danvolkens, and he is going to take it from here with tightening up the styles.

- This splits the user show sidebar into a partial that is then used on the
profile edit view. It updates the sidebar to display a different link based on
the controller (view for edit, manage for view). This makes the manage profile
view look similar to the user view.
