MPR121 or other capacitive touch sensor

[Nick Willis]

I'd really like to use NM for my touch sensor nodes. I can see there is support for the TTP226/TTP229 but the pads are tiny on those boards and I'd like much bigger buttons for light switches etc. I've built my own pads with wires soldered to copper tape which is stuck to a printed piece of card.
Detection of touch input I've tried directly from the Arduino pins - which works but you're limited on pins. I've also got a powered node up with an MPR121 using the Adafruit_MPR121 library which is working well.

I'd like to bring it into the NM fold since I want to run my touch sensors on batteries and NM is great for battery nodes!

What's my best approach here? Maybe the MPR121 could be added as a new sensor type? Or perhaps I'm better using something else?

@nick-willis interesting thanks, adding it to the queue for the next release (https://github.com/mysensors/NodeManager/issues/365)
