Allow matchType as a value for the include parameter

[jvendetti]

End user reported the desire to retrieve "matchType" when using the include parameter with the search endpoint:

Using the 'Term Search' endpoint in your REST API, I would like to receive the 'properties' field alongside the 'matchType' field. Right now it is only possible to receive the 'matchType' if I don't add the 'include' parameter. Using 'include=properties' removes the 'matchType' and the 'include' does not accept 'matchType'. Also, 'include=all' does not work. Is it possible to receive both fields in one response?

The following example call:

http://data.bioontology.org/search?q=melanoma&include=matchType,properties

... results in a 400 error:

"The `include` query string parameter cannot accept matchType, please use only prefLabel, synonym, definition, notation, cui, semanticType, properties"

Leaving matchType out of the list of allowed include parameters appears to have been an oversight.
