[TIMOB-18554] Research various JS tools to compare capabilities against our standards

I am working on creating formatting files for all languages we use regularly at Appcelerator, as well as configuration files for static/dynamic analysis I’d like to create one for JavaScript. We have a standards guide here, but I want to create a complete set: http://docs.appcelerator.com/titanium/latest/#!/guide/JavaScript_Coding_Standards * A file we can use to format JavaScript ourselves in our favorite editor * A command-line tool we can use to validate that JS has been formatted correctly in PRs from contributors * An updating of the JavaScript standards in Studio to match so that promote this style in our own products as well. The tools should offer the following: * node.js package * Grunt plugin * Sublime plugin * Atom plugin * Gulp plugin Review the list of capabilities across these tools and put a checkmark in each column where it has that ability: https://wiki.appcelerator.org/display/eng/JavaScript+Tooling For the tool with the most capabilities, create a formatting file and check it into https://github.com/appcelerator/appc-standards/tree/master/languages/js
