Add way to install IntelliJ codestyle locally to project

[chrisbanes]

At the moment the --apply-to-idea parameter installs the codestyle globally to the IJ/AS profile, and changes the project to use that global profile.

I prefer to bundle the codestyle locally in the project's .idea folder (example). It would be nice if there was a nice way to do that. I'd even argue it should be the default (but we're probably past that now).

Thank you for the example, Chris!
If what we need can be configured through project's .idea then there is absolutely no reason to modify anything globally. I'll update --apply-to-idea.

I never commit those .idea folders and I'd use the current solution. I guess having both would not harm either way.

Added ktlint --apply-to-idea-project (0.22.0+).
