Make the organization page happy!

Add CLI import/export support for organizations

Output headers on export

Implement CLI user import/export in a well formatted CSV file. Name and
email address are the only supported fields at the moment.

This patch partially reverts the previous database migration patch which
added a primary key to the table on the `thread_id` column. This column
cannot be used, because there may be multiple entries for thread_id = 0.

adds the database portion of regex support for ticket filters.

Add the current backend to the list results output
Add a --limit switch to support limit results sent to a command like
`migrate`

Allows for backend listing, file listing, single file dump and file
migration.
