filter testing

[Edgar Pettijohn]

I've written a perl script to help test filters. It can be found at:
http://www.pettijohn-web.com/filter-test.pl

Its not 100% complete but it should be helpful enough in finding common 
problems. Such as forgetting fflush() in awk filters or swapping the 
session id and opaque tokens.

If you run into any problems please send examples of what you expected 
vs what you got. Or patches would be great.
