Added two new methods: hasParametersParameter() and getParametersParameter().

* hasParametersParameter() will test a sub-key of an array of parameters
  if it exists: ?task[part_number]=10 would mean hasParametersParameter('task', 'part_number')
  would return true.

* getParametersParameter() actually gets the value if it exists. So with the above
  request, getParametersParameter('task', 'part_number') would return 10.

Last change in here is that the WWW-Authenticate header was sending back the realm
as Accthub, which is untrue. Changed that to Secure Website so it is more generic.
