scroll groups in qtile

scroll_groups.py

"""
mod-m and mod-n scroll between groups right and left respectively.

Depending on the number of screens used the integers will need changing (where there are 3s, 4s and 5s below).
The numbers below are for 3 groups on one screen and 2 on the other - knowing that it can be worked out (hopefully!)
