Title: Redis::Mutex#locked? predicate

Hi!

Very nice library. I'm going to use it for our web-sites in production, but we're in need for some predicate, that tells us about mutex state. So I've implemented `locked?` method and wrote some tests for it.

What do you think about it?

P.S. I've tried but failed to understand what `@locking` variable means.
