JS: End with newline

[claudiojs]

Hi! Thanks for writing this task!

I was wondering why I can't use this option:
https://github.com/beautify-web/js-beautify/blob/master/js/lib/beautify.js#L75

Then I figured it out that the task allways inserts a newline after beautifying a JavaScript file - something that I dont't want to. It is unfortunately impossible to configure it with the parameter options. Could you please change this?

Here is the code that I mean:

grunt-jsbeautifier/lib/jsbeautifier.js

Line 62 in c0a47d0

return [jsBeautify.js, config.js, true];

and here:

grunt-jsbeautifier/lib/jsbeautifier.js

Line 86 in c0a47d0

// jsbeautifier would skip the line terminator for js files

This was done way before "end_with_newline" options was added to js-beautify, this was the pull request for it #5.

There is also a pull request #46 for fix but test cases are failing. I will get it correct and honor "end_with_newline"

Pushed fix in version 0.2.9
