[GRASSLIST:4420] Re: bug fixes for tcltkgrass for GRASS 5.3

Maciek,

Thanks for your input. Based on this, I've committed a number of improvement
or fixes to the CVS as of today. See below

Added. Also added entries for anisotrophy

Fixed. Added option to enter or not enter metadata on new vector points
created. To do this, s.to.vect now opens in an xterm where you can enter
metadata if the -p flag is not checked.

Renamed in menus to interpolation from raster contours

Added module (already written by someone else) for v.surf.rst. Note that a
couple of options (anisotrophy and another) are left out because the module
is already as large as my screen and may not show up completely on lower
resolution screens. I don't know why there is not an option for a vertical
scroll-bar in the 5.3 menu module builder, but the modules are limited
(practically) to the vertical screen resolution.

Renamed menus, leaving off reference to lat-long and calling idw2 'alternate
method'. I don't know what the difference is either.

As I explained in my earlier message to you (but not to the list), this
would be nice but isn't possible without someone with greater tcltk
expertise than me making bubble help available in the menu hierarchy below
the top level.

Thanks again for your input.
