Since we do not package the KWSys source tree directly and always
merge snapshots of its content into other project subtrees, we
should carry the .gitattributes file into the other projects to
that the attributes apply in their source trees too.

Configure GitSetup scripts for KWSys.  Run them from a single
SetupForDevelopment.sh script.

Add a script implementing our standard "git gerrit-push" alias.  When
invoked, first check that the current branch is a named topic.  Then
fetch 'master' from the 'gerrit' remote repository so the local
repository can compute a minimal pack to push.  Finally, push the topic
to the 'gerrit' remote as "refs/for/master/$topic".

Add a .gitattributes line to match both "config.sample" and any config
file added by the containing project.

Add the "export-ignore" attribute to all such files.  Remove the
suggestion from the README since this should not be a responsibility
of the including project.

Prompt the user to configure user.name and user.email interactively.
