Make VC helper fields configurable
Adds KALAMAR_VC_HELPER_FIELDS environment variable and vc_helper_fields
configuration option to add or remove fields from the virtual corpus
builder at runtime.
Syntax: KALAMAR_VC_HELPER_FIELDS=+award:text,-docTitle
+name:type adds a field
-name removes a field
The result is always sorted alphabetically. Analogous to
KALAMAR_HINT_FOUNDRIES (aa6709c).
