Enhance Citation view for 'contributor'

[cameron]

There is a problem with the citation generated from the Cite/Attribute link. If the copyright owner is an organization, and therefore listed as the “contributor”, the title of the organization is parsed like a name and makes no sense. (For example: ©Tides Foundation & Funders Workgroup for Sustainable Production and Consumption, the author’s listed as “Consumption, T.F.&F.W.f.S.P.a.”. ).This can be fixed like the citation view for 'creator' by adding code to support non abbreviation by including a @ at the front of the 'contributor' entry.
