[plt-scheme] Planet HTTP 403 errors

jmj, Steve:

What happens if you try to visit the relevant link in your web
browser? Here's one example url, which I got from the planet
commandline tool:

% planet url sbloch tiles.plt 1 14
http://planet.plt-scheme.org/servlets/planet-servlet.ss?lang=%224.2.3.2%22&name=%22tiles.plt%22&maj=1&min-lo=14&min-hi=%23f&path=%28%22sbloch%22%29

You should get a few screenfuls of gibberish, starting like this:
