Implemented the `linter-cpplint` package

I've created the `linter-cpplint` package:

https://github.com/Nathan-Smith/linter-cpplint
https://atom.io/packages/linter-cpplint

It runs the [Google Style Guild C++ Linter](http://google-styleguide.googlecode.com/svn/trunk/cpplint/cpplint.py) which mostly follows the [Google Style Guide](http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml)
