winhlp32 implementation

Hi, all!

I intend to implement winhlp32 utility looks like native one (font size 
changing, GID and CNT files support, etc...).
Please, share your opinion, has this idea any sense, or *.hlp died long ago 
and only few persons need it?

Inspired by bug http://bugs.winehq.org/show_bug.cgi?id=5926

Thanks.
