This allows code in lib, model etc to not worry about GeoAlchemy
versions. This assume the correct library installed, as the check has
been done when starting up.
Some improvements on the endpoints that return the contents of the
harvest objects:
* Nicer URLs with redirects to the old ones
* Returning the raw harvest object content is available on the main
harvest extension, so just redirect there
* Support for showing the original document of a harvest object, if
present
* Suport for defining a custom XSLT for the HTML view, via
ckanext.spatial.harvest.xslt_html_content
ckanext.spatial.harvest.xslt_html_content_original
Tests are passing, apart from a couple which didn't work before:
* test_functional.py -> functional/test_package.py (3 failures in 4)
* functional/test_dataset_map.py (1 fail in 1)
There may be some code errors still untested.
Renamed Validator -> Validators to make more sense.
Search results coming from the default CKAN search (which are received
via the `search` method of the `IPackageController` interface) are
filtered to only contain the ones intersecting the provided bbox.
The search form temporarily shows a text field, which will be replaced
by a nice map widget.
