Add a new argument to the SourceColumn class to flag a column as
sortable. The SourceColum will generate a request querystring to
be used as the table header archor href. The SingleObjectListView
will capture the querystring and call the order_by on the queryset
to sort it.

Instead of inserting the path of the apps into the Python app,
the apps are now referenced by their full import path.
This app name claves with external or native Python libraries.
Example: Mayan statistics app vs. Python new statistics library.
Every app reference is now prepended with 'mayan.apps'.
Existing config.yml files need to be updated manually.
