typo

Fix unit tests for mysql-based document filter.
Refactor mysql document filter test
Introduce a base class for the 3 DocumentFilter implementations
Tidy build_filter in announcements, policies, & publications controllers
Put all the tests for presenter objects into test/unit/presenters

Make sure they all are PresenterTestCase subclasses and fix any errors that occur because of that (database access mostly).  Add rake test:presenters so we can just run them too, if we're so inclined.
Use FakeSearch by default in test

For those tests that want to exercise what they do with "real" search results, we also provide NotQuiteAsFakeSearch.  This supplies a Rummageable implementation to allow storing content and a DocumentFilter implementation to allow fetching content.  This can be invoked at the class level with with_not_quite_as_fake_search.
Send the publication_type_id of Consultations to Rummageable
Use FakeSearch by default in cucumber

Allow for tagging a feature @not-quite-as-fake-search to ask it to use NotQuiteAsFakeSearch (Rummageable and DocumentFilter) if we need it.

Note: This means enabling mocha in our cucumbers, not sure how we feel about that.
