Extend DataB-module with table view

Problem/Motivation

The Datab module now produces a simple list of files. But the response includes more information, like attachments, the amount of a specification. We would like to show these as wel in table form:

Proposed resolution

• Add an option to "Show as table". So the default operation of the module will not be changed.
• Create a table view with the columns "Description", "Date", "Amount".
• Include the attachments in the table.
• Add the option in administration to choose one of the "demo"-bsn values to test different outputs.
