Title: Add scrollReachedTop and scrollReachedBottom events for infinite scroll

Added events to core, and provided a tutorial that demonstrates infinite
scroll. It's a little untidy in that when you add rows to the data the
grid adds them to the end irrespective of where you put them in your data
array. But if you have the grid sorted, then it works.

This is based off the publicApi pull request, as the publicApi is needed on
which to create these events.
