Allow to run Scalastyle builder independently of the other project's builders

[dotta]

Compiling scala code takes time. It would be desiderable for Scalastyle to have its own builder allow to run the Scalastyle builder independently of the other project's builders, as users may not always have Build Automatically on (in fact, if you are a Scala compiler hacker, you never ever have Build Automatically ;))

Actually, scalastyle has its own builder. So, let me refine my feature request :)

What I'd like to have is an option for running the Scalastyle builder on save without running the Scala builder. That should clarify what in the ticket's description I was mentioning Build Automatically.

Basically, would it be possible to provide a Build Scalastyle on save action that would be used when Build Automatically is disabled?

I think this is a duplicate of #6, so I'm closing that one. If necessary, we can add the options for checking a single package or project as well. Actually, package would be quite hard, so we say folder instead.
