I move <grass/config.h> to the top of V_support.c and added it to
another file that was missing it.  I also added a macro around
<grass/vask.h> to prevent multiple inclusion.  Updated documentation,
also.

The files could probably use some #ifdef HAVE_CURSES_H macros...
Let me know if it's still broke and I'll add the above macro where
needed.
