shouldn’t need those gems in production
clarified requirements

- legistar tasks depend on legistar module
- Shellwords, shapefile stuff not needed apparently
improved log messages from legistar module

- let the user know where they’ll find the log file
- don’t show verbose info messages on console (but do show error messages there!)
- show a “.” for each fetch attempt to convey progress
- “pp” lib seems to be necessary… otherwise we get ‘uninitialized constant PP’ error on production environments.
