Ilya Pekelny 5f3fcf1123 Uses explicit imports for _
Previously `_` was monkeypatched in tests/core.py and bin/keystone-*.
This meant that if a developer was not running the tests exactly as
the documentation described they would not work. Even importing
certain modules in a interactive Python interpreter would fail unless
keystone.tests was imported first. Monkeypatching was removed and
explicit import for `_` was added.
