Webpack 2.x compatibility

[GabeMedrash]

So far as I can tell, in Webpack 2.x, --colors is no longer a valid CLI option. --color is now the supported option. Running this plugin using Webpack 2.1.0-beta.4 (current as of today) produces a huge console error, though the meat of it is: Unknown argument: colors.

Changing the option to --color in lib/runWebPackSync.js fixes the issue, though I'm assuming would break compatibility with Webpack 1.x.

Looks like removing colors options will not break anything. You could provide a PR, and I feel all tests will be completed. So if no issues will be in tests I'll accept your PR.
