* 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.

+ 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.
