Improved Undo Feature in Configuration Manager

The Undo Changes feature, available in the Session Definition Sets dialog in Configuration Manager, has been improved:

Changes can be undone for individual sessions, function windows, all sessions, or all function windows.
Changes are no longer forgotten after leaving the Session Definition Sets dialog – they persist for the whole lifetime of the Configuration Manager process.
Values revert to the point when the dialog was first opened or the last time they were applied to runtime from the same dialog.
