WebInject - Web/HTTP Test Tool

I just grabbed WebInject yesterday, as I was looking to add some extended
monitoring to Nagios.

My original plan was to install webinject in /usr/local/bin, and have the
scripts located under /usr/local/nagios/libexec/scripts. This brought up
an interesting bug, which I see was mentioned here and here. It looks like
work is being done on the second one.

The other issue is related to temporary files. With the above setup in
mind, the nagios user wouldn't have write access to anything but the
nagios/var directory, however, it seems that WebInject wants to take a
temporary file, and put it inside the directory where the testcases are
located. This should be easily changed out to using something simple like
mktemp (or Perl equivalent).
