Fix version of delayed_job_active_record (for postgres 8.4
compatibility)
Fix imports with repeated authors.
make names unique in the other importer as well.
Fixed typo in OpenUrl Conference Poster type_uri. Fixed incorrect method name for publication_date in open_url_context_hash. Added tests for both.

Fix error if publication doesn't have a publisher.
fix syntax problem - I guess rescue can't be used exactly as I was trying to.

Add id to Promotion that we can match on when updating. Shorten description to 200 chars or less and terminate with ellipse or at end sentence.
HTML-encode keywords and descriptions before building XML.
