changes to files that don't need to be changed

Add lib/tasks/annotate.rake to the Manifest, up the revision to push out to rubyforge

trying to figure this git stuff out ;)
This reverts commit a7e0b8cb.

It's become a convention to clean up massive numbers of models by grouping them logically into
subdirectories (e.g. putting everything related to finances under app/models/finances).
This commit refactors the single line that retrieves the model class into a method that can
properly check for alternative class names.
