Added search aliases, along with tests. tests currently fail when
searching on aliases: for some reason that I have yet to understand, at
this point in the test, there are only two items left in the Article
table (pk'd 1 and 2). I have *no* idea where the third one went,
especially since it exists in the test that creates it. Maybe is it
deleted in the test tear down?
Premeptively bumped to version 0.0.5.
