remove dependency on ckan.model.ResourceGroup

[florianm]

ckan.model.ResourceGroup was removed from CKAN somewhere in mid 2014. CKAN 2.3a (Nov 2014) runs fine with latest ckanext-qa (qa update and showing resource ratings), but crashes on links under /qa due to reports.py depending on the removed ckan.model.ResourceGroup.

Relevant stack trace (nb. my CKAN lives in /mnt/ckan/ rather than /usr/lib/ckan):

Deleting the lines containing "ResourceGroup" in ckanext-qa/ckanext/qa/reports.py, deleting the .pyc in site-packages (CKAN_HOME/lib/python2.7/site-packages/ckanext_qa-0.3-py2.7.egg/ckanext/qa/reports.pyc) and restarting the server fixes the server error on accessing qa/dataset/five_stars, /qa/dataset/broken_resource_links, and /qa/organisation/broken_resource_links.

Sounds good, a pull request would be even better.
