The latest flake8 release in now 1.5, which pulls in pep8: 1.3.4a0
The upgrade pep8 has changes to what it picks up as lint.
Making code base compatible, so that new devs can install pep8
from PyPI and not have friction over the version difference.
Currently using these ignores in the config file:
```
[pep8]
ignore = E124,E125,E126
```
Ignoring these since they are difficult to squash while maintaining
an 80 char line length, and appear spurious.
Should address later.
Updates Travis config, README, and pip requirements to reflect change.
Removes TRANSFORM_TYPE from protocol, since it is unused.
Also, removes use of ndict as a member of protocol, since it's
import there was for the TRANSFORM_TYPE. Changed to
utils.protocol_utils instead.
