Fix authorization handshake to use POST rather than GET

See merge request !1

Updated authorization handshake to use POST rather than GET when fetching the access/refresh tokens. Incremented library version from 1.3.0 to 1.4.0

Modified to accomodate Genesys API change for Accession delete and Accession delete by id. Trimmed '/' from end of host URI to prevent case of '//' in API URI which Genesys server no longer accomodates.

Extended the UpsertResponse to include an enumeration for the item-level action type.  Updated version to 1.2

Check for Json formatted API responses, and parse out error message for GenesysApiException. Altered unit test to provide better error messages.

1. Changed Accession Upsert method to return an array UpsertResponse objects
2. Changed Accession Name upsert method to return an array of UpsertResponse objects
3. Added an Accession GetJson method to retrieve an Accession based on Genesys ID
4. Altered the async calls to return control to the calling thread.
5. Updated Organization API SaveBlurp to include summary string
6. Fixed serialization of Accession "mlsstat" property to be "mlsStat"
7. Fixed serialization of Accession DuplSite property. Was incorrectly serializing as "suplSite"
8. Added support for new Accession properties "historic", "acceUrl", and "remarks"
9. Added AccessionIdComparer equality comparer class to support identifying duplicate accessions
10. Fixed mispelling of GeoData property "Longitude".
11. Update version of assembly from 1.0 to 1.1
12. Updated unit test console app to leverage updates.

Added ability to configure the library by passing parameters to constructors, rather than only through the configuration file.

Extracted interfaces from classes to support a Mock pattern, allowing an implementor to develop without a GeneSys server.  Implemented remaining API methods.

Restructured classes. Implemented Api methods for Crops, Me, Accession, Organization.  Imlemented auth code to get tokens based on code or refreshtoken.

Initial project creation, including library, console test app, and Sandcastle Help generation project.
