* utils/hbmk2/hbmk2.prg
    + added tricky feature which attempts to autodetect whether
      a script is meant to be run on an interactive CUI as
      opposed to the default command line (CLI, aka GTCGI) mode.
      It makes it possible to keep cmdline oriented scripts
      running using GTCGI, while full-screen apps are run
      using GTWIN and friends without code changes. F.e.
      /tests apps can be run this way easily.
    ; scripts can force to use CLI by using:
      'REQUEST HB_GT_CGI_DEFAULT'
    ; scripts can switch to CUI mode explicitly by running
      this code:
      #ifdef __HBSCRIPT__HBSHELL
         hbshell_gtInteractive()
      #endif
      Experimental, might change to something more elegant.

  * tests/db_brows.prg
    ! fixed CUI for unicode and readded CUI drawing elements

  * tests/sbartest.prg
