Adding show view for users.

Use partials for displaying details shown when viewing a user. Some of these partials have specific CSS for another use, so we will likely want to tweak this.
minor: put emails in unstyled ul and simplify

Just found out that render(@collection) returns nil for emtpy collections. So that is usefull for putting messages about the emtpy collection in an or clause.
reverted simplification - not good to have 'none set' in a %ul
Show different ticket characteristics when viewing the users versus when listing the tickets. Give a message if a user has no tickets.
