Recursive ipaddr dependencies in ciscoconfparse breaks pip (version 1.2.11)

[alexd-siaras]

Installation fails due to a failure to find ipaddr:

The problem is only loosely related to the commit you referenced; the referenced commit was part of my first attempt to undo the old local_py kludge fixes in the repo.

The root of the problem was a recursive dependency in setup.py and ciscoconfparse/__init__.py; I used local_py because I did not notice the recursive deps. Props to @CrackerJackMack, who hawkeye'd the issue in 30 seconds.

This is fixed in ciscoconfparse version 1.2.12.
