- Added a SEARCHINIT statement to initialize search parameters for a
   faster BOYER-MOORE search algorithm.

   Syntax:
    SEARCHINIT criteria,caseSensitive

     criteria      = A string expression with the search criteria in the same
                     format used by PCBoard (ie, "THIS & THAT | BOB")
     caseSensitive = A boolean flag (TRUE to force a case sensitive search,
                     FALSE otherwise)
