Added a bunch of new features:

- Debug mode is now configurable in the configuration file. This way, we don't have to edit versioned files to disable it on production systems.
- Recent correspondents filter (enable in configuration file)
- Document actions: Edit tags and correspondents on multiple documents at once
- Replaced month list filter with date drilldown
- Sortable document count columns on Tag and Correspondent admin
- Last correspondence column on Correspondent admin
- Save and edit next functionality for document editing
