Rework the users#show page to avoid custom column css

This uses bootstrap instead, ensuring the map shows before the
text on small screens, but to the right of it on md+ widths. The
height of the map also changes at this breakpoint instead of being
based on the menu width (body.small).

The account edit page was also changed to match the content_map
changes, and a full width map is now used. This can be changed, if
required, using bootstrap breakpoints but I like it as it is.
