Switch to latest version of pylint and fix runtime bug

[DavidPal]

This PR fixes issues:

• https://github.com/edaniszewski/pylint-quotes/issues/23
• https://github.com/edaniszewski/pylint-quotes/issues/24

List of changes:

• Fix runtime version check, which is causing error in the latest versions of pylint.
• Increase version number to 0.2.2
• Fix order of imports to make isort happy

Testing:

• I have created a simple python file x.py with content:

  
  A = "x"
  B = 'y'

C = """hello world """

D = ''' hello world '''

def foo(): '''Foo''' pass

- I have installed the package and its dependencies: `pip install --editable . `
- I have run `pylint --load-plugins=pylint_quotes x.py`

---
I have tried tried running unit tests with `make test`, but get a lot of identical errors:
`TypeError: 'module' object is not callable`. The same errors show up in Travis.

Travis builds also fail for Python 3.4 and 3.5.

Thanks for the contribution - this looks great.

I'll merge this in and try to work through the import errors seen in tests. I suspect there was just a change in module naming in pylint so now this is importing a module instead of a function.
