* Fix extras as a list of dicts
* Fix SOLR dates syntax - needed a Z
* Basic tests for this updated ckan harvester
* Now require CKAN 2.0 to be able to be able to save these packages in package_show form. Take advantage of this now we are such various imports from are definitely available, such as munge_tag.
* Add back compatibility for other harvesters supplying restful-like package_dicts to _create_or_update_package
TODO add back in the ability to harvest pre 2.0 CKANs with the RESTful calls (fallback or maybe configurable)
* Adapt test_queue to harvest source datasets
* Don't use the same mock harvester on different datasets as it messes
the tests up
* Skip auth tests for the time being
Until now, harvest jobs were set to Finished just after sending all
objects to the fetch stage. Now every time the run command is run, jobs
are set to Running, and all previous Running jobs are checked to see if
all harvest objects have a state of Complete or Error. Only then the job
is flagged as Finished.
`harvest_source_create` and `harvest_source_update` now call
`package_create` and `package_update` respectively, making sure to
define a 'harvest_source' type. The returned dict uses the db_to_form
schema.
