Added udev rule for device access

I originally wanted to match only the PowerMate device. Unfortunately,
due to the way the the PowerMate library searches for the device, any
/dev/input/event* without proper permissions generates an fatal error.

Therefore, the following does NOT work:

ENV{ID_MODEL}=="Griffin_PowerMate", MODE="660", GROUP="input"

This forces us to use the vaguer committed rule to match all
/dev/input/event* to group input and perm 660. :-/
