[GRASS5] new scripts for GRASS 5.7

[Markus Neteler]

Michael,

I didn't look at the package yet but I would like to
remind that only scripts using 'g.parser' should be
accepted in GRASS 5.7.
Maybe you have added 'g.parser' support in your new
scripts, then they might be integrated directly.
Otherwise please add the 'g.parser' related stuff.

Thanks

 Markus
