Add 'Property', 'Contact', and/or 'Tenancy' columns to the Documents page

The columns shown in the Documents page seem arbitrary. For example, the 'Folder' column is shown, but not 'Property', 'Contact', or 'Tenancy'.

It would be useful to show these columns, as well, or make the columns configurable.

The use case is that it makes little sense to use folders for different properties when documents can be assigned to properties and then use the filters. But, this means that it would be more useful to be able to see the property in a column when viewing documents in a single folder that apply to multiple properties. Similar use cases for the other columns mentioned.
