Fixed an error at import time when categories have long names
Improved feed queuing efficiency

Filtering is done directly in the DB instead of fetching all the data and
running should_update(). updatefeeds is approx. 5x faster and tasks generate
much less queries.
Reworked the queuing code, now 1 jour update period
More ignores in the favicon fetching
Added a logger for rq warnings / errors
Moved static assets to a 'core' app
Implemented the Google Reader API.

Google Reader clients should Just Work™ by just switching the API root from
http://www.google.com/ to https://feedhq.org/, assuming they use Google's
ClientLogin authentication mechanism.
Added a coverage target
Fixed the pep8-naming warnings
Increased the title size
Updated feed on save
Added more types to ignored favicon content types
