Fixed debug typos
Added underscore decorators to "private" methods in Warden.py
Added db existence checking
General fixes
Warden setup script improvements, better option passing and parsing and argument handling
Started work on new configuration method. Using ConfigParser. This removed the awkwardness of python module behaviour and can be placed anywhere on the system.
Better command line argument handling
Normalisation of paths
Update `install_requires` and `dependency_links`.
Removed unused code
Removed quote marks from conf
Remove the bogus diamond version whose presence was to force the version in the dependency_link to be used.) We now install explicitly.
