More detailed error messages

[grantwinney]

The RestResponse.Content field looks something like this when it has an error in it, when it's returned in GhostAPI.cs. I could modify the error I return to take some of that data into account, to make errors more meaningful...

{
	"errors": [{
		"message": "Validation error, cannot save post.",
		"context": "Validation failed for 'posts'",
		"type": "ValidationError",
		"details": [{
				"keyword": "additionalProperties",
				"dataPath": "",
				"schemaPath": "#/additionalProperties",
				"params": {
					"additionalProperty": "Posts"
				},
				"message": "should NOT have additional properties"
			},
			{
				"keyword": "required",
				"dataPath": "",
				"schemaPath": "#/required",
				"params": {
					"missingProperty": "posts"
				},
				"message": "should have required property 'posts'"
			}
		],
		"property": "posts",
		"help": null,
		"code": null,
		"id": "b50a7fd0-500a-11e9-a8e0-472301ed00b2"
	}]
}
