[GRASS-dev] rough draft of release announcement and blurb

[Hamish]

Hi,

please review:

https://trac.osgeo.org/grass/browser/grass-web/trunk/announces/abstract_grass640.txt

https://trac.osgeo.org/grass/browser/grass-web/trunk/announces/announce_grass640.html


I put a frame background on the main announcement but the main CSS's <h3>
forces a background color. I'm not a CSS expert so not sure how to fix
that.

since the new feature list goes back to new things since GRASS 6.2.3
(circa 9000 edits along this branch) it is likely that some quite major
things have been forgotten, although IMO the list should not resemble a
10 page changelog with every new feature. Request for many eyeballs.

thanks to Markus & Markus for their contributions already.
