* fixed warnings for overriden node and edge colors

* removed tool tip from color scheme
* changed names in project setup screen
This change shows the files in the code view minimized, if more than 5. This greatly improves performance, because code
and annotations won't get loaded until needed. Files including declarations or definitions of the active symbol are
still expanded. The number of references in each file is now shown in it's title bar. Clicking the title bar allows for
expanding and collapsing as well now.
This change styles the nodes in the QtGraphView. Since Stylesheets can't be applied to QGraphicsItems, the style
implementation was done in the source files. The containers for public/protected/private nodes are now subclassed from
QtGraphNode as QtGraphNodeAccess, including a helper class QtAccessArrow for indicating the opened/colapsed state.
