Allow profile to specify vocabularies to be included in metadata records

[tedhabermann]

The mdProfile descriptions (in json) need to be extended to include information about vocabularies that are included in the profile.

This extension must include:

1. information that a user needs to select the profile and attach it to a record
2. information that mdEditor needs to facilitate inclusion of the vocabulary in a metadata record: (vocabulary properties, terms, and definitions).

For example, in the case of vocabularies from scienceBase, the sciencebase id for the vocabulary provides access to the vocabulary home page and to items in the vocabulary. For example, the Datacite Contributor Type vocabulary has the id 6123b2c3bac0c745ec5f2199
