#11 Admin Page enhancement

[Anonymous]

Add a new column for all types listed in the admin
pages (member types, contact types, volunteer types,
etc.) to show how many times each type is used. Make a
link to click on this number to go to a search results
page to list those records by group. (What about
contact and volunteer types?)

Some types are required but outside of them, allow deletion
of a type if the count is zero. If count is > zero, can not
delete.
