Updated Display Last Update on Tile View, Grid Block and Carousel Simple when display Create date style prop

[Bob]

At the moment it's only possible to select the publish date in the tile view properties.

It would be nice to allow the updated date to also be chosen.

I like showing the date on mine, but it's a bit odd when it's an old item so the date is from years ago, even though it's on the top of the stack.

I've updated Tile View, Grid Block and Carousel to display the Last update data when the style property is set to display publish date (this is now standardized across all addons).
