Fixes for v1.7 release

[rgrp]

A place to list crucial fixes for v1.7 release:

• Related Item has comments on index page (they should not show up here -- why is this happening!)
• Related item should be to left of history (history could in fact move to RHS)
  • What about losing icons since we duplicate for related item
• Related item plus sign is very poorly aligned within box
  • Add related items should be in drop down like for resources (?) to make it easy to add items
  • Hover should show a title that gives some information about what related are (not at all clear)
