Set base jscs to ^1.12.0

I know there's been a few of these requests in the past, but I think 1.12.0 is significant enough to merit bumping the lower bounds of the gulp-jscs package.

Ideally, this would be to eventually support allowing options like auto-fixing through, considering thats a whopper of a feature to be missing through gulp.

You and everyone else seems to be confused about how semver works.

tl;dr There's no need for bumping, you'll get the latest jscs up until before 2.0.0.

You answered me on twitter, anyway-- sorry! I know that semver will auto-upgrade with a ^ character-- I was proposing bumping the contract in your package.json to state you support from 1.12.0 onward.

Use case here meaning, if I was an absolute stickler for package.json versions, and at some point you allow using flags available in later versions of jscs, updating the semver here would allow me to see up to what API version you've verified things working.

This is less about what version is packaged and more of, "What flags can I actually pass in?"
