Rename Executive Director section on Profile to Contacts

[cielf]

Summary

Rename the Executive Director section on Profile to Contacts

Why

It has more than Executive Director information in it

Details

This is more complicated than it sounds
You have to:

1/ Rename the section itself
2/ Add a heading for Executive Director within the card (that is now a Contacts card) for both view and edit (and both partner and organization, but you may get that for free)
3/ Change the partner profile sections functionality in My Organization to use Contacts instead of Executive Director. I'm pretty sure you'll need to rename that partials on the profile to reflect the new name.
4/ Migrate the partner profile sections so any of them that have Executive Director now have Contacts
5/ Update tests
6/ Update the user guide -- both the organization section and the partner profile section

Criteria for completion

• behaviour as described
• automated tests adjusted appropriately
• guide updated
