* utils/hbrun/hbrun.prg
+ Added support for registering/unregistering .hbs file type
in Windows registry. Based on .reg files provided by Mindaugas
(with modifications and unregister support). I changed the way
defaulticon entry is made, but it still doesn't appear, maybe
I need reboot or something. Pls test it.
Usage (from cmdline):
-r - register for current user
-ra - register for all users (requires admin rights)
-u - unregister for current user
-ua - unregister for all users (requires admin rights)
Tested on Win7 using current user only.
NOTE: regedit (the tool used for registration) doesn't
return errorlevels on error, so it's not possible
to write correct feedback (so hbrun always shows
success).
