Minor Wording Change to Edit Relationship Types

As per http://forum.civicrm.org/index.php?topic=24413.new;topicseen#new

I think it would be more clear if, on the screen where you add/edit Relationship types, the options for "Contact Type A" and "Contact Type B" said "All Contacts, Individual, Organization ..." instead of the current "-select -, Individual, Organization ...". It took me a while to realize that I could just leave that on "select" when I wanted to have a relationship that didn't require a specific contact type.
