logic: Refactored undo redo stack

* Store MessageActivateTokens instead of original view messages
* Renamed FeatureController to ActivationController
* Remove all non-activation messages from undo redo stack after reindexing project
* Added MessageShowReference to undo redo stack
* Added MessageScrollGraph for restoring graph view scroll position
* Fixed MessageGraphNodeMove not saved for bundles
* Refactored tokenIds and nodeNames in SearchMatch and MessageActivateTokens
* Refactored SearchController
* Fixed file expansion on undoing/redoing after switching code view mode
* Fixed redundant graph animation due to present qualifier nodes
* Fixed no restoring of graph node expansion when showing overview in between
