Add common style guide pre-made rules

[SBoudrias]

Configuration is nice, but having to set this on multiple project or often is a bit tedious.

It'd be super nice if jscs offered a set of predefined rules matching common styles guides like Idiomatic, Google style guide, BSD KNF, etc etc

Then you'd just have to set an option to check using the defined guide. { "style_guide": "idiomatic" }

In esformatter these are called presets. There's currently "default" (match google code js style guide) and "jquery" (matching jQuery style guide, which overlaps a lot of idiomatic.js). You can pick a preset, then override the specific settings you want to be different. That seems like a good route for this project as well.

For a jQuery/idiomatic preset, the configuration in jQuery UI might be a good starting point: https://github.com/jquery/jquery-ui/blob/master/.jscs.json
