Adding prefill logic to infiniteScrollHelper

[fstani]

I've added a prefill logic to the plugin, it checks to see if when the load finishes if it has loaded enough data to fill the area, otherwise it will trigger a load again.

@rogden do you think this is a good update to the plugin?

Hey @fstani Thanks for the contribution! I had not thought of this use case but it certainly seems helpful. I'm wondering if it should be built vs being an option. Can you think of a use case where someone wouldn't want the plugin to load the next set of data if container height doesn't fill enough of the screen to cause the user to scroll, triggering the next load?

hmmm, @rogden I actually don't know, I thought of adding it as an option, since for our case it seemed necessary but I did not take a lot of time to think over other uses cases, so that's the only reason why it is optional. But I personally would rather keep it an option, that could be defaulted to true and ask the community if we should remove the option, some projects might have some specificity that not having the option might break the functionality for them.
