Consolidate organisation views

Previously, the show view for high profile groups (AKA. sub-organisations) 
had some differences from the normal organisation show view.  The HPG
show page wasn't cutting the mustard so we're taking out the differences.

The only thing HPGs need to show which normal orgs don't are the HPGs
parent organisations. These have been redesigned to be below the org's title.
See the pivotal ticket for screen-shots.
