new templates and "gnome-feedback"

[Alexander Kirillov <kirillov math sunysb edu>]

Hi all: 

following discussion we had here some time ago, I wrote a separate doc
"Reporting GNOME bugs and other feedback", and Dan put it in
gnome-core, so starting with the next release of gnome-core you can
refer to this doc (using URL gnome-help:gnome-feedback) instead of
previous bug-submission instructions. Should make it easier to change
when (God forbid) bug database is moved, and for ditribution packagers
who may want to replace it with their own support info.

I updated gnome-app-template to show how it should be done; I also
changed somewhat <releaseinfo> part and, following suggestion of
jfleck, added lang attribute. Please take a look - and update your docs
when you have time. I didn't change applet templates yet - Telsa,
jfleck: should I do it or you would rather do it yourself?

By the way: it would be nice if all people responsible for  docs
took time to make sure that the corresponding entries in DocTable 
(http://developer.gnome.org/projects/gdp/doctable/)
are up to date; some of them seem to be terribly outdated. 

Best,
Sasha
