JSHint checkstyle reporter

##Changes of this Fork This is fork extends the checkstyle reporter of sublimeye. The reporter is now retrieved by a factory function. For each creation of a reporter it saves all files that were reported to have errors. When JSHint is finished the plugin offers a generateReport() method to retrieve a single checkstyle XML string containing the results of all these files.

For JSHint Report Plugin (Jenkins Checkstyle Plugin)

Modified version of JSHint checkstyle reporter that supports different severity levels: High, Medium, Low.

This reporter will add colors to your JSHint Trend reports in Jenkins, produced by JSHint Report Plugin.

Getting Started

It is designed to use together with grunt (& grunt-contrib-jshint plugin).

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install jshint-jenkins-checkstyle-reporter --save-dev

Also you may want to install it globally by passing -g flag. That allows you to use this reporter in all your projects.

Once the reporter has been installed, it may be enabled inside your Gruntfile in jshint configuration:

jshint: {
	options: {
		reporter: require('jshint-jenkins-checkstyle-reporter'),
		reporterOutput: 'report-jshint-checkstyle.xml'
	}
}

P.S. Don't try to fix reporter for Jenkins Validations Plugin. The plugin has hardcoded severity level and must be fixed first.

P.P.S. Perhaps these modifications should/will be pulled into JSHint checkstyle reporter some day . Or will be added as additional reporter.
