FIX: permalinks table: increase limit of url column, make url index unique
Allow restoring from backups in development mode even if the setting is
off.
FIX: Failed incoming emails could create empty topics

A failure condition is eliminated where a topic would be created, but post
creation would fail, leaving the forum with a topic without any posts.
By asking PostCreator to create the topic instead, inside of its
transaction, this failure condition is eliminated.

Additionally, attachments are restored to working status. Previously,
the attachment code would build up the post raw, but then drop it and
not do anything with the result (creating orphaned uploads). By actually
placing the raw value back in the options hash, it is included in the
created post.
