Carousel format enhancements

[thomas-topway-it]

• enhance carousel with fixed height (changes are consistent with adaptiveHeight if set), images are vertically centered
• hide caption container on small screens if title is not set
• fix additional nested slide, see Extra div is added inside .slick-slide in version 1.8.0 - 1.8.1 kenwheeler/slick#3148 and Rows causing unexpected nested Div in latest kenwheeler/slick#3110

@thomas-topway-it the test to MW 1.39 is not passing... for SMW 5.0 release, MW 1.39 is more important than 1.35, so, if you can adjust to at least the 1.39 to pass, it will probably be merged.

noted, I'm sorry for the delay
