OpenDataPhilly Importer

This is a first stab at a Python script which uses the OpenDataPhilly and CKAN APIs to migrate data from ODP to a CKAN instance. Most information isn't being migrated yet, but all datasources with their names and links back to the primary source are migrated.

Right now the script is a pretty simple set of functions; depending on how complex this ends up becoming, it may be a good idea to create some basic classes to make the ETL process a bit smoother.
