Improve upload manager

[voltan]

widget module upload manager is very nice, I use it in some other modules. But if we add some options to upload manager, it has been very powerfull

1- Move js settings from usr/module/widget/template/admin/widget-carousel.phtml to www/static/vendor/jquery/extension/fileupload-setting.js as default setting ( it just url need php code and it be set in template )

2- Add default design ( whit css and template ), perhaps as helper

3- support ZF2 ProgressBar. it very helpful at big files upload
