Fix ignored and select settings interface with pycodestyle
On https://github.com/PyCQA/pycodestyle/pull/722 they refused to fix their interface. When passing the list arguments as `ignore` and `select` settings to `pycodestyle`, it is required to pass a python list as `["E201", "E501"]`, instead of a string `"E201,E501"`, otherwise they will cause the issue pointed on: https://github.com/tomv564/LSP/issues/244#issuecomment-358753274
