[stellation-res] Checkout caution, and associated changes

[Dave Shields <shields@xxxxxxxxxxxxxx>]

I just noted that doing

 cvs checkout -P org.eclipse.stellation

gives you about 13 MB of stuff you don't need, since
all our website content, including the download directory
and displayed javadoc, lives under org.eclipse.stellation.
This is the way the Eclipse website is run: whenever you view a
page there is almost always a CVS checkout being done on your behalf
to retrieve the content.

You really only need to do

 cvs checkout -P org.eclipse.stellation/plugins

I noted there was a copy of cpl-v10.html (our license) in
org.eclipse.stellation, but not in org.eclipse.stellation/plugins,
so I have just added a copy of cpl to the plugins directory,
and also added a caution to the core doc/build.html file.

Note that checking out just 'plugins' results in downloading
almost 6 MB of stuff, which is one of the reasons I'be been working
on providing current builds.

It would be nice to provide a CVS module to assist checking out just
the plugins directory, but I don't have the needed CVS privileges to
add this.
