Added wotkit harvester with one source for now (airquality) ported from sensetecnic/sensors. Allows module configuration through the harvester UI to configure which sources to "harvest" into wotkit. Additionally creates a ckan dataset and populates it with resources for each sensor which link to wotkit (still buggy).

Configure the modules through harvest UI as json with params such as: {
"gather_sensors":

	[{
		"module": "airquality",
		"package_name": "air quality sensors"
	}]
}
