Grand test fixup (#138)

* start fixing up tests

* fix up tests + automate with drone

* fiddle with linting

* messing about with drone.yml

* some more fiddling

* hmmm

* add cache

* add vendor directory

* verbose

* ci updates

* update some little things

+// Package propertyimage contains the implementation for the image property. All
+// applications are strongly encouraged to use the interface instead of this
+// concrete definition. The interfaces allow applications to consume only the
+// types and properties needed and be independent of the go-fed implementation
+// if another alternative implementation is created. This package is
+// code-generated and subject to the same license as the go-fed tool used to
+// generate it.
+//
+// This package is independent of other types' and properties' implementations
+// by having a Manager injected into it to act as a factory for the concrete
+// implementations. The implementations have been generated into their own
+// separate subpackages for each vocabulary.
+//
+// Strongly consider using the interfaces instead of this package.
