Update hacking for Python33.3.0

The repo is Python 3 now, so update hacking to version 3.0 which
supports Python 3.

Fix:
F601 dictionary key 'cr_to_rp' repeated with different values
F841 local variable 'excep' is assigned to but never used
F821 undefined name 'excep'
E305 expected 2 blank lines after class or function definition, found 1
E731 do not assign a lambda expression, use a def

Blacklist:
W504 line break after binary operator

Update hacking extension for newer flake8 version.
