* Remove useless .Table() from db usage
This is handled via TableName() already
* Optimization: omit file-list fetching for old torrents
* Use seperate tables for reports & files on sukebei
* Fix invalid pages in nav if <5 pages total
The FileList that is read with GetTorrents is empty, as it's only loaded with
GetTorrentById. So, always insert the new FileList on the database, and rely on
the unique_index to avoid duplications.
