Use a dummy citation if one was not extracted.

For unusual citations, such as a web URL, ParsCit might not be able to extract
a citation.  When this happens, the array of citations is empty (when only one
possible citation was in the file to parse).  Create a "dummy" citation object
directly, and set its string and title to be the full reference text.
Updated query to use new name for reference.

The foreign key from referenced_work_guesses to work_references should have
been going to works instead.  The update to the schema to fix this causes the
WorkReference result class to have a new name for its relationship to the
referenced_work_guesses table.
Fetch the appropriate persona, or die trying.
Updated query to use nested join to personas table.
Added note about search query being incorrect.

The search query needs to have additional conditions on the JOIN to the
personas table, which is not supported by DBIx::Class.  Most likely, a custom
view will be needed.
Use persona_id, not user/algorithm/etc., with guess.
Advanced version to 0.004.

This is the first explicitly stable version.
Added version info for 0.004 and previous versions.

Earlier versions did not have a 'Changes' file.
