Pylint-quotes

* remove pylint-quotes/pylint dependency on setup ([PR6](https://github.com/edaniszewski/pylint-quotes/pull/6))

* adds 'smart quote' mode which allows greater flexibility around string quote escaping ([PR1](https://github.com/edaniszewski/pylint-quotes/pull/1))
* fixes bugs where a module/class/function defined with only a docstring (no body elements) would crash the checker due to idx out of range error
* adds test suite

- fixes bug where multi-line function signatures were not using proper docstring row number for triple quote lookup before validation.
