3.0b2 database schema migrations

[Barry Warsaw]

The following database schema migrations are required. This is a release blocker for 3.0 final. Add more to this bug as you find them.

 * Change news_prefix_subject_too -> nntp_prefix_subject_too

 * Remove nntp_host from table mailing list

[Barry Warsaw (barry)]

* archive and archive_private -> archive_policy

See LP: 967238

[Barry Warsaw (barry)]

Make that LP: #967238

[Barry Warsaw (barry)]

news_moderation -> newsgroup_moderation

[Barry Warsaw (barry)]

include_list_post_header should probably be renamed too because RFC 2369 says that announce lists should still include the List-Post header, but set its value to NO.

I'm not sure what the flag should be called though.

[Barry Warsaw (barry)]

include_list_post_header -> allow_list_posts

When set to False, add List_Post: NO
