added remctl helper file called volume-helper.py
this script smoothly moves volume up/down over 3sec (large step)
made volume-up and volume-down call it (volume-helper.py +/-)
this commit also contains a bugfix by quentin: previously
"amixer set PCM -3dB" would recognize -3dB as "option 3dB",
fixed by means of using "--" in the calling convention
