[CMD-HELP]

[CMD-HELP]
Add a help.exe utility to replace the old built-in command "help" in cmd.exe (i.e. do it the Win2k3 way).
This way, if somebody runs a personalized command-line environment which provides its own help command, one can use the personalized help command and not the standard one (e.g. the "help" command of RosBE).

Adapted by myself from a patch by Lee Schroeder.
CORE-5701 #resolve #comment Committed in revision 59832, thanks :) I use a trick to be able to compile the utility (use: ninja cmd_help) because doing "ninja help" has a signification in ninja (signaled by AmineKhaldi).
