Show apps in name order.

Prior to this, they were in whatever order they came from the metadata.
This resulted in weidrness because the repo which was updated last will
have its apps shown last. We are trying to move away from the repo
update order being important.

In the future, this sort order should take into account better
heuristics, but for now this is at least deterministic.
