History:
Feb 24, 2002 V1.00 Wilfried Mestdagh <wilfried@mestdagh.biz> created a
             property editor for LineEnd property. I moved his code ti this
             new unit so that it is compatible with Delphi 6.
Jan 19, 2003 V5.00 First pre-release for ICS-SSL. New major version number.
             Skipped version numbers to mach wsocket.pas major version number.
May 31, 2004 V5.01 Used ICSDEFS.INC the same way as in other units
