Issue 405 - Section C

This includes some updates to the issue 405 - section c - that is to style the profile pages ( ie: https://demo.opensourcecurrency.org/groups/21#memberships/52 )

I consider the work still incomplete as the view users a partial that is different from the current style. Would require to address it tomorrow.

Is the layout satisfactory or would it need some changes?

The markdown text was added to the immediate right of the image. The controls / links were put to the right corner ( with the image ). I think the request was the differently.
