* Introduce new setting requireAdjustmentsConfirmation
* Refactor adjustments presets activation handling
* If requireAdjustmentsConfirmation true, show confirmation dialog before firing preset activation workflow
* If requireAdjustmentsConfirmation false, immediately activate preset (like before)
* Addresses #1110
