Updating NEWS for 1.6.8 release.

[Rob Browning]

If you have time, could those of you who have committed changes to 1.6
(since 1.6.7) check out a current 1.6 tree, look over the output of

  cvs -qz5 diff -u -r release_1-6-7

and make sure that all of your changes have appropriate NEWS entries?

Thanks
