Changed the order of the "main" scripts in the bower.json file

If you use the AngularJs Yeoman Generator in your daily workflow, the `grunt serve` command (who fires the wiredep task, that is defined in Gruntfile.js) will include the bower_components installed scripts in the main index.html but, it always puts the jwplayer.html5.js script before the jwplayer.js script. That causes The following error is shown in the javascript console of the browser: "Uncaught ReferenceError: jwplayer is not defined". It's simple to understand that, the base jwplayer.js should be loaded before. This pull request seems to solve this.

I will use that script for production purposes so, if you decide to not merge my pull request I will be forced to fork it and maintain separately because it's mandatory that the grunt build process works seamless and automated through a Capistrano deploy script.

I'm working at serious IT company on a daily basis, so whatever you want to ask me, please feel free to contact. I will appreciate as soon as possible merge because we have deadlines to accomplish.

Thanks for all !
