Creation of a link to webwork3 from the ww2 instructor tools.
removed classlisteditor3 and homeworkseteditor3 from %showeditors
Changed things so that the dancer components of webwork3 are served via apache using cgi.
Forogt to copy over changes to a .dist
Added proxypass lines back in
Changed the configuration to speed things up a bit.  Now static files in js or css or images are served directly by apache in the new configuration, saving some calls to dancer.
Changed config files so they are all in one place.  Change dispatch.fcgi to only start one instance of perl.
