Choose to show/hide editor name on original texts belonging to citing work

[tcouch]

Add checkbox to citing works to choose whether to show/hide editor name on original texts belonging to that work when there is only one reference.

Some citing works should show references like this: Smith 1.2.3-5
And others should show references like this: 1.2.3-5

All original texts should continue to include editor name when there are two or more references: Smith 1.2.3-5 | Jones 4.5.6-8

Or put another way:
Some original texts will need to display the editor name as part of the reference, even when there’s only one, others will not. This should be determined at the citing work level. Can we have a checkbox to toggle this?
