Luacheck: Automatic Option should be off by default

[Stanzilla]

This option does not make it very clear that you have to disable it to get it working with a .luacheckrc file in your project directory. If that is not what it actually does, then that might be a bug but when it is enabled and I have a config in the project, the config is ignored and default is used instead.

Thanks for this. Also I noticed that the "path to .luacheckrc" actually wants the path to the directory containing .luacheckrc rather than the path to the file itself.
