Javascript: add sample jscsrc file

:eyeglasses: @ajacksified @spladug I've added a [jscs](https://github.com/jscs-dev/node-jscs) sample config.  Please give this a whirl and let me know if you take issue with any of the settings.  I've based it on the style guide and used discretion for things not covered.

You can use it via the command line:
`jscs path/to/file.js`

Or there are also plugins for [sublime](https://sublime.wbond.net/packages/SublimeLinter-jscs) and [vim](https://github.com/scrooloose/syntastic/blob/master/syntax_checkers/javascript/jscs.vim)

I'd also advise making this a standard part of builds ([gulp](https://www.npmjs.org/package/gulp-jscs/), [grunt](https://www.npmjs.org/package/grunt-jscs))

Let me know if you have any questions!
