Push several changes.

- New theme.
- Word filter.
- Added experimental file harvester mode which isn't complete.
- Added file tree (open http://ip:port/filetree)
- Fix security bug in the File Handler.
- Change the way thumbnails are stored.
- Added thread worker info page.
- Made the file queue table sort-able with javascript.
- Add support for HTTPS.
- Added 15 different file queue download priorities.
- Support the new changes in the 4chan API (boards.json file).

Probably there is more.
