[GRASS5] Changes between 5.0.1 release and current CVS head

[Helena]

I have mistakenly emailed this just to Glynn, but some comments from
others would be useful
so I am re-sending it to the list.

 I assume that the above are Bob's improvements and they need some
testing.
 We will try this week but getting more people to try it would help.
 I have put a copy of Bob's message at the end - testing keyframe
 animations may be harder for those who haven't done it before
 but testing the large site files is easy and it makes a big difference
 if you have million points (e.g. from LIDAR) and want to zoom into
 a small place. So if these work they should be included.

 These are probably important fixes by Alfonso Vitti so they should be
 included - Alfonso, John Harrop, Jaro, and whoever had a chance to work
with it can
 you comment on it?

 these are new modules - they work but they are being further developed
 and could benefit from testing. So they can be included but I suggest
 that they are in the same category as the g3d stuff - not being built
 by defualt.
