Is null filtering is not working on hstore field

[nemesifier]

Test needed, could you send a pull request with one?

OK, I am preparing PR with fix. I can split it into 2 commits (test & fix). Fix is pretty easy:
in django_hstore/query.py line 127

elif lookup_type in ['contains', 'icontains']:
.... #add this case
elif lookup_type == 'isnull':
    return super(HStoreWhereNode, self).make_atom(child, qn, connection)
#end patch
else:
...

i've just created a branch issues/null-filtering, please open 1 pull request to that branch and push commits as soon as you have them, me and @niwibe will look into it as soon as we have some free time

I need help, did PR but into wrong branch. Could you advise how can I fix that?

[nemesifier]

ok not a big deal for me, let's wait for @niwibe 's input

[niwinz]

No problem for me for pull request to master, I review it this afternoon and merge it. Seems very simple patch ;)

@nemesisdesign if you believe that the patch is ready, you can merge it without my review ;)

Thanks to both!
