Update user count, it's currently 4,671,530 according to Alys. So the million count goes up to 4 and the texts mentioning the number of users is supposed to display this count. There have been two texts and the count is only in one of them with the other hardcoded. Seems like a good thing to not actually calculate the number of users for performance reasons. resolves #11790
