Some new features

Hi, I created a branch of collective.carousel.

My branch add the italian translation and change a little the javascript of the carousel, checking if the viewlet has a special class "blockAutoScroll". In this way is simple to customize and block the autoscroll feature.

For accessibility reason italian site must not start automatically animations.

I've done some other changes, maybe other not good (sorry, this is my first github project...)

Off Topic: note that all your project page (plone.org and pypi) still point to the SVN collective.
