Subject: [PATCH] - improved version of robots.txt (delete your old
 htroot/robots.txt before updating):   - robots.txt is a servlet now   - no
 need to rewrite the whole file each time a section is added or removed   -
 user-defined disallows, added manually, won't be overwritten anymore - new
 config-setting: httpd.robots.txt, holding names of the disallowed sections
