Go to group on different screen

go_to_group.py

"""
The idea here is that we've split the groups across 2 monitors, 0 and 1,
and each group is locked to one of these monitors. The groups here are
named '1', '2', '3', 'q', 'w', 'e', and 3 of these are locked to each
screen (see line 9). These can be changed of course, but update lines 9, 13 and 19.
