Robot udev rule

[ripleymj]

We probably need a udev rule for the robots. This is what is used on the lab laptops:

# On precise, for some reason, USER and GROUP are getting ignored.
# So setting mode = 0666 for now.
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="kobuki*", MODE:="0666", GROUP:="dialout", SYMLINK+="kobuki"
# Bluetooth module (currently not supported and may have problems)
# SUBSYSTEM=="tty", ATTRS{address}=="00:00:00:41:48:22", MODE:="0666", GROUP:="dialout", SYMLINK+="kobuki"

57-kobuki.rules is identical to the issue text. I'll draft a PR later.
