hi, 

the attached patch (to be applied to the current CVS tree) implements
the diagram window idea i mentioned a few days ago:

- a new menu item "View/Diagram tree" in the toolbox toggles the
  diagram tree window.

- the window shows a tree with the currently open diagrams as its nodes.

- each node can be expanded to show the diagram's objects as an icon +
  the object name, text or type (depending on whether the object has
  a "name" or "text" properties).

- clicking on a diagram node brings its window to the foreground, and
  clicking on an object's node also selects the object within the
  diagram.

- the tree content is kept in sync as you add/remove diagrams/objects,
  or change the "name" property (i haven't found the way to
  automatically update the "text" when you change it, but it is
  updated when you click on the object's node).

- a new dia preference can be set specifying whether to show the
  diagram window at startup or not (it would be very easy to add
  preferences to set the window's dimensions if you think it's
  useful, probably in a new tab on the preferences dialog). 

i've not tested these new features in depth, but they seem to work
pretty well here. any feedback will be highly appreciated!

i hope the unidiff rocks enough to get in :-)

best regards,

jao
