Add devices to S3 hacker port menu

[CarolHazlett]

Is it possible to move blocks to another menu? I would like to see an RGB LED block in the Scribbler menu so I could program one to run in the hacker port. That way I could make custom colored patterns using timed photography and have some control over the brightness of the LED for the light graphics you have seen me do with the S2 and S3. Since the Scribbler is in C now wouldn't it be possible?
