Remove javascript comments from .jshintrc before loading

JSHint supports javascript style comments in .jshintrc. When a project contains such config file and brackets opens it, brackets-jshint fails to parse it because of comments.

Please use the following method to strip comments before you do JSON.parse in main.js

    /**
     * Removes JavaScript comments from a string by replacing
     * everything between block comments and everything after
     * single-line comments in a non-greedy way.
     *
     * English version of the regex:
     *   match '/*'
     *   then match zero or more instances of any character (incl. \n)
     *   except for instances of '* /' (without a space, obv.)
     *   then match '* /' (again, without a space)
     *
     * @param {string} str a string with potential JavaScript comments.
     * @returns {string} a string without JavaScript comments.
     */
    function removeComments(str) {
        str = str || "";

        str = str.replace(/\/\*(?:(?!\*\/)[\s\S])*\*\//g, "");
        str = str.replace(/\/\/[^\n\r]*/g, ""); // Everything after '//'

        return str;
    }

This is the same approach jshint uses with its command line interface.

I considered giving a pull request, but somehow you are using non consistent line endings in main.js and it mess up the patch. So I did not bother.

I don't mind the line endings changing - can you just submit a PR?
