FileServerServlet doesn't decode escape sequencies in URL?

Hi all,

the FileServerServlet seems to suffer from a serious bug - it doesn't
decode the escape sequences in URL.

Example: http://www.server.com/path/file%20name.png

This should return a file named "file name.png". But it doesn't -
instead it searches for  file named "file%20name.png" and since there is
no such file it returns Error 404.

This would be a one liner fix but it's weird that it hasn't been noticed
before...
