Android: Use SwipeRefreshLayout in MainActivity 

The main reason why I'm adding this isn't actually to allow
users to swipe down to refresh, it's to add a loading indicator.
Considering that the Storage Access Framework can be slow for
folders with many items (many subfolders?), not showing a
loading indicator might give users the impression that adding
a folder resulted in nothing happening even though Dolphin is
scanning for games in the background. But I suppose letting
users swipe down to refresh is a nice bonus with the change.
