[P064] Add Separate Gesture events option

[tonhuisman]

To resolve a forum complaint

Feature:

• Add setting to generate a separate/independent event for gestures (<TaskName>#Swipe=<gesture>), so gestures can be handled independently from Interval events, or when interval events are disabled (Interval = 0).
• Allows Gestures to be processed when measuring R/G/B Colors
• Other code improvements
• Updated documentation

TODO:

• Testing by requester (confirmed)
