Add pocket computer light support to Speaker. #289
This makes use of new pocket computer light access peripherals have and adds said functionality to speaker. If noisy pocket has made sound the pocket computer light will turn blue for a second.
This showcases use of this feature to future peripheral makes and allows end user to quickly find which pocket in their inventory was making sound.
Its a little thing but oh so nice. (And would be helpful for people with many pockets. )[<- This close parenthesis is sponsored by @Cruor ]
EDIT: Now a gif cause someone requested it. In this image pocket makes sound every 2 seconds resulting in blink action to showcase color change. Also color changed to lighBlue on request to make it more visible.
