Reverse Sorting by default for Hooks

[mcDevnagh]

I've created a hook to download RSS/Atom feeds, and I want to sort by most recent, according to the published date as provided by the feed. Because plato only supports publication year and added (which I think should be different from the published date), I encoded the publish date into the file name. The only problem is, when I set the sort-method to file-name, it orders them with the older entries first. I would like an option in [[libraries.hooks]] to reverse that, much like the current Reverse Order check in the UI
