- Moved thumbs folder to public_html/
- Users can supply custom thumbs of any size and the system will treat
them like normal image
- Removed distinction between various thumb sizes in file system
- Introduced custom rewrite rule, which isn't exactly good-looking, but
its benefits far outweigh its shortcomings
- Loading up to 75 times faster (was: 100-300ms, is: 4-10ms on my
machine) thanks to removal of PHP proxying
