Command line flags don't correspond to shakeOptions

I'm using 0.15.10 and I don't see the analog of -w in shakeOptions. Similarly, --verbose doesn't accept an argument while shakeVerbosity does.
Also, see #49.

Yes, it's not intended that all options are available in both ShakeOptions and on the command line - although it is the usual state of affairs, and #49 is an instance where it probably should be available in both.

You can get all the verbosity levels in shake using a combination of --verbose (which increases the verbosity) and --quiet (decrease verbosity). Use --verbosity --verbosity to increase by two levels.

Printing the directory (aka -w) is mostly there because of Make. I don't think it's a really useful feature, but if you want it, you can hardcode it in Shake yourself with putStrLn =<< getCurrentDirectory.

I think --verbose and --quiet were the unclear ones (now help text is improved), while color is missing, but tracked at #49. If you see anything else you think would be useful to expose let me know.
