- Move synchronize/details panel flag to more generic ModifyContext
- Do not use MarkAsGarbage as means of enforcing not to show object in details panel to avoid leaving objects in invalid state if undo called. Check ed graph membership instead
- Get rid of leaky namechanged delegates
- Allows for migration to isolated synchronization in the future
- Removes conflation of having to synchronize and update views when modifying frontend document
- Decouples concept of a specific view to update from generic frontend graph modifications
