Columns are displayed incorrectly in carousels

Fixed and tested.

While I was in there I noticed that the code to set row_classes was duplicated. The first instance of it will never be used if the if statement evaluates false. And it is set again inside the if statement.

Looks like there is a bit more wrong with the use of columns. It's intended that if you have 2 columns, the content should appear side by side in a single carousel. I'm not seeing that either before or after this MR.

Yeah there's something wrong with the structure in certain circumstances related to adding another level of divs. I'm seeing the wrong number of closing divs when there's two columns but three items.

Trying to make sense of what's going on and fixing it.

Ok the problem when there is an uneven number of items causing missing closing tags should be fixed now. This was actually a problem before introducing the row div it just didn't break the html enough to be noticeable before.

I also fixed the positioning of captions with the multi column layout.

Thanks
