- Added a DOWNLOAD statement to allow downloading files from PPL.

   Syntax:
    DOWNLOAD "CMD;CMD;CMD"

   The string passed to DOWNLOAD is a list of commands in the same format
   as what a user would type after a D or DB command.  If a file name
   for download is specified here it must be downloadable according to
   the criteria established in the FSEC and DLPATH.LST files.  If it is
   necessary to download a file not normally available via the FSEC
   and/or DLPATH.LST files the FLAG statement may be used to force it
   into the list of files to download.
