* Converted Tonks' public requests into the new system, and cleaned up relevant code.
* Added missing repeat dialogue for one of the events
* Added event flags
* Fixed pulse_hover animation resetting
* Fixed Hermione's hold book pose
* Fixed minor story inconsistencies and spelling
* Fixed Tonks' hair colour not resetting
* Blocked Hermione from being summoned during Tonks' investigation
* Blocked Snape from being summoned during the day (It's not like he'd help anyway)
* Updated tutorials to reflect these changes
* Added checkpoints to forbid the editor from rolling back to menu context
* Added forced checkpoint for when the editor is being opened to avoid rolling back to before it was opened (by opening a console for example)
* Alleviated the issue for when the game tries to recover from the place it cannot stop rolling back, but version var is unavailable because of it being not initialized in that moment
