Fixed a few consumer bugs and added an exporter

Rename exporter to export and fixt some debugging

Account for files not matching the sender/title pattern

Added a safety note

Wrong regex on the name parser

Renamed the command to something slightly less ambiguous

src/documents/management/commands/document_exporter.py
