Users can now choose which key columns appear in the Documents list view, including name, tags, partner, owner, type, and creation date. This makes the list easier to use on smaller phone screens by letting each user hide fields they do not need.

There isn't enough place on a default phone screen to display the 6
default fields of the documents list view*. Unfortunately, since none of
those fields are marked as optional, a user cannot customize the view
and decide to toggle those fields.

This commit adds the optional attribute on several fields to allow some
customization.

* concerned fields
- name
- tag_ids
- partner_id
- owner_id
- type
- create_date
