* include/hbextern.ch
  * source/rtl/Makefile
  + source/rtl/base64c.c
  + source/rtl/base64.prg
    + Added HB_BASE64ENCODE(), HB_BASE64DECODE() to core.
      They were copied from hbtip and hbvpdf and currently
      the decoder is .prg code while encoding is .c code.
      Latter has one TOFIX for an error situation.

  * contrib/hbtip/encurl.prg
  * contrib/hbtip/thtml.prg
  * contrib/hbtip/sessid.prg
  * contrib/hbtip/popcln.prg
  * contrib/hbtip/sendmail.prg
  * contrib/hbtip/tip.ch
  * contrib/hbtip/cgi.prg
  * contrib/hbtip/url.prg
  * contrib/hbtip/encqp.prg
  * contrib/hbtip/base64x.c
  * contrib/hbtip/httpcln.prg
  * contrib/hbtip/client.prg
  * contrib/hbtip/encoder.prg
  * contrib/hbtip/smtpcln.prg
  * contrib/hbtip/encb64.prg
  * contrib/hbtip/mail.prg
  * contrib/hbtip/credent.prg
  * contrib/hbtip/ftpcln.prg
    + Added TOFIXes, QUESTIONs
    ! Fixed to use hb_MemoRead() instead of MemoRead() in one place.
    ! Fixed a wrong error checks after FCreate() calls.
    ! Fixed to use Len( hb_inetCRLF ) instead of hardwired length.
    ! Using hb_ntos() instead of Str() in POP3 commands.
    * Changed explicit values to manifest constants (F_ERROR)
    * Changed high ASCII chars in source to Chr() representation,
      now source can be edited with any editor.
    ! Added missing copyright header to tip.ch. Although this header
      seems to be unnecessary.
    ! TipMail:MakeBoundary() to not add any date punctuations in the ID.
    ! Fixed tIPClientFTP:fileSize() to not return permantent zero.
    % Heavier optimizations and cleanup in TIpClientSmtp().
    % Optimizations.
    * Formatting.
    ; Please test.
