Fixing up setup.py and making sure routes exist for site and publisher reports

Removed some unused commented out code

Remove prettyprinting unless DEBUG is set in env and add a new
test for actually making the calls.

Adds new columns to the table to store the relevant organisation, but also
allows for the metric/value to be stored so that it can eventually contain
different metrics than the default

Packages up the data from Analytics.

- Makes sure we get the right account by requiring a new googleanalytics.account
config option which will be used to look up the correct account details.

- Changed the model to use the sqlalchemy orm and made sure it does the updates correctly.

- Still need to collect further info (such as the group details)
