Subject: [PATCH] Close #25 and Close #10

Fixed scroll bars not appearing. Also implemented load/save of
Collections; tied the Library to a collection (libraries are per-project);
Most of the File menu works now. Library manager works. Ready to start
working on the drag and drop library pallette and tabbed page display at
this point.
