Added code to raise an error if trying to paste a step in reference to a step that has been deleted by another user (eg: paste before, paste after or paste replace)

Added handlers for new treeview events of NodeCopy and ClipboardStatus
Added exception handlers to handle the exception of trying to use a deleted step as a reference point for a paste operation (before, after or replace)
Added code to set the MyCopyStep property to the value of the new step added in a paste replace operation
