Proposed patch for the bug

Build ID: I20080617-2000

Steps To Reproduce:
1. Open the Instance Management View
2. Close the Instance Management View
3. Create a new instance of some device
4. Open the eclipse log file and see that some exceptions for "widget is disposed" are shown

This happens because one of the UI classes on the View adds a listener to the InstanceEventManager, and when it is closed and some InstanceEvent happens, the listener is still informed and it tries to execute some operations on the UI and the UI is not available anymore (it has been disposed).

Attached is the proposed patch for this bug. It consists of removing the listener from InstanceEventManager when the dispose() method of the UI class is called.
