Carousel - addition of a quickselector Type

Hi there!

I came up with this change when I expanded the Bootstrap elements to my needs.
May needs a rework to requestUpdate and show image field only when display of quickselect is active.
Also the style of the bootstrap has to adapt. By default the text-ident value is set to -999px; however to display images or text (numbers) you may need to change this by adding stylesheets to either override the default bootstrap text indent. and also for images a width/height auto.

I'd be happy to see you using this little but useful Addition :)
