Adds a very simple rake task that excludes our most expensive tests over jobs.
Adds methods for lookup of the canonical record and the thumbnail to the core object.
Adds a helper that returns either a thumbnail object or the stringified class name of the canonical object for the given core record, which we should be able to use to build type-appropriate default icons.  Also adds the partial that leverages this new helper.
Merge branch 'feature/thumbs_and_canonization' into feature/redo_characterization_and_thumbnails

Merging in my own changes from a different branch because they're similar enough to be one.
