Protobuild linux fixes, probablly should have included with the last PR

I probably should have included this with the last pull request, sorry. Also if you guys want to keep &lt;binary&gt; instead of &lt;reference&gt; you'll need to add ".config" files, or set local copy to false.
We can't do this because the Gtk# components are not installed on the Windows Box which does the linux building. This was why we had to put these files in Dependencies.
