Proposed Jetty Security Fix

[Aaron Mulder <am...@alumni.princeton.edu>]

I couldn't figure out how to fix the problem properly.  So to avoid
the hole, here's a patch to reject deployments if web.xml includes
security settings and geronimo-web.xml does not.  This way, at least
it's impossible to end up thinking you have security in place when
actually you do not.
