Activities: Change labels on the loop

[rcass]

loop is a very confusing term for clients, so best to have the labels be not technical so that anyone could understand.

So the activities image loop on the activities page, it current looks like this:

Instead of Activity Image Looper, I think Activity Image Carousel would be more clear. And you could even add a descriptive text below with more info. For example, "Below add the images you want to appear as a carousel with the activity).

Secondly, Loop Row is also not very clear to a client, perhaps something like Activity Image would be more accurate.
