r.in.arctiff and r.out.arctiff updated again

Dear GRASS community,

thanks to Leslie Apollon from LAS - hopefully the scripts are working
correctly now! I have added n-s-resol. and e-w-resol. support and
corrected the calculation of the boundaries both in

   - r.out.arctiff (which was already included in GRASS 4.2.1) and
   - r.in.arctiff

If you still find errors, please let me know.
Find these two GRASS scripts on my homepage:

       http://www.geog.uni-hannover.de/users/neteler/

  They will be added to forthcoming GRASS 4.2.1 update.

  Best regards

     Markus Neteler
