Add scores, scoredvotes, recommendations to api

Multichamber fixes and tests update #MemopolMiniHackaton

REMOVE DB.SQLITE

Fix tests on master

See the 2 previous commits for example reasons to do that !

0.3.0 introduces status_code generation which causes the test to fail
with FixtureCreated on travis.

Otherwise tests might become broken as a side effect of an upgrade in
these packages. And that's hard to figure out ;)

Fixed url conflicts

Display votes with recommendation only

Added proposal autocomplete, upgrade to DAL v3

Added API

Use Country.get_absolute_url in templates

Also, use django-responsediff instead of manually updating test
fixtures.
