Support CKAN 2.10

[avdata99]

Adding support for CKAN 2.10.

Related to CKAN#6787

CKAN master + harvest + DCAT looks good

This extensions requires ckanext-harvest and Harvest#496 to be merged (I sent a PR to that PR to update it here)

With those PR merged, locally, I get all tests ok

@avdata99 Only one minor thing to get the <2.9 tests passing:

diff --git a/ckanext/dcat/urls.py b/ckanext/dcat/urls.py
index cd209e7..7b92535 100644

     if not tk.check_ckan_version(min_version='2.9'):

         external = kwargs.pop('_external', False)

Also could you replace all usage of qualified=True in url_for with _external=True? Thanks!

[avdata99]

All suggestions applied @amercader The qualified=True to _external=True solved the problem

Thanks @avdata99!
