CVS commit by staikos: 

- fix a memory corruption problem in main due to double delete of the mainwindow
in some cases

- only update the necessary parts of the data manager.  this is implemented in a
rather slow way (the code is ~O(n^2)) but it is more reliable for now.  In the
future we should tell the datamanager what to do, as opposed to telling it to
update and having it determine what needs to be updated.
