Bryce Denney ec0fbf18bc - convert nearly all bx_options to parameter form. All options that have 
been converted into parameters temporarily have the letter "O" appended
  to their name.  I don't want to keep it this way, but it has helped
  in the conversion process because the compiler refuses to compile the
  old uses of the name.  Before I started using the "O" trick, there were
  many bugs like this:   if (bx_options.diskc.present) {...}
  This was legal with the new parameters, but it was testing whether the
  parameter structure had been created, instead of testing the value of
  the present parameter.  Renaming present to Opresent turns this into
  a compile error, which points out the incorrect use of the param.
- the "--disable-control-panel" no longer works, I'm afraid.  I can no
  longer support this and continue progress.
