python3.x merge caused issues with python2.x compat

instead of importing division from future we simply use int() to cast
floats to integers.

nosetests: on python2.7 passes
python2 test_ago.py: passes
python3 test_ago.py: passes

TODO: Does nosetests work with python3.x?

branch 'default'
changed ago.py
changed test_ago.py
