need help cleaning up user directory and php rules

[Edho P Arief]

...and 10 hours later I fixed it by myself. Tested with most common
cases, also ensured basic logic. Can be cleaned up better (or perhaps
squash more bugs, if any) but I'm too sleepy right now.

Also probably rather slow. My own connection is currently slow and I
only tried this on remote system.

        listen 80;
        server_name genshiken.unit.itb.ac.id;

use for improvement (or deletion)
