Add a new command-line option -T that's the same as -t, but it does

Add a new command-line option -T that's the same as -t, but it does
not do DirectoryRoot checking. This assumes:

   1. command-line options are prefered over Config directives
   2. we want to maintain current behavior while making
      life easier for mass vhosting
   3. everybody's happy

I leave the decision to whether apachectl should use -t or -T
to others.
