Fix feedback to control surfaces without touch sensitivity

[jtackaberry]

Reaticulate reflects CCs back to control surfaces in realtime when feedback is enabled. This is needed for many control surfaces, and works fine for those with touch-enabled motorized faders where the motor disengages when the fader is touched.

But some control surfaces don't need this CC reflection and these incoming events can make the experience janky if there is a RTT delay such that the fader is on another value by the time it receives back the reflected event.

Create an option "Reflect incoming CCs" with the values

• Always
• Only during playback
