Config improvement

See: https://github.com/AtomLinter/Linter/issues/203

I also changed the default value for the config.

Now `inline view = true `and `statusBar = false`.

Do you agree?

Can you please read these config values then map them to the correct value in the new enum? That way we won't reset people's settings with this upgrade. You'll be converting 8 states to 4, but some of those 8 don't make a lot of sense anyway, so you should be able to do something reasonable :smile:
