in APC, and will needs to ensure such data is purged when the table
structures change.

This adds ability to delete properties on list deletion

This patch (which needs further development), introduces an extra field to
the %attachment table to store a file's name, in the event that two files
with the same content are stored in the database with differing names. In
such a case, the name is stored in the %attachment table. This allows the
attachment to specify a different name each time the same file is attached
to something in the system.

* Rename config var enable_html_thread to enable_richtext
* Copy config var name_format to agent_name_format and client_name_format
  and delete it

This stems from a bug not clearing the org_id when removing organizations

Also make forms deleteble by marking them as deleted and hiding them from
the form listing. This ensures that custom data always has a link back to
the form.

These fields have been consolidated into the `flags` column.
