Overhauled file index:

	Renamed `FileIndex` to `Index`
	The index JSON format now supports versioning and uses "flat" entries
	`Index` now preloads all files when loaded
	Removed `SyncIndexFS` and `AsyncIndexFS`
	Added `IndexFS.reloadFiles` (and `*Sync`)
Renamed `FetchFS.preloadFile` to `FetchFS.preload`
Removed `FetchFS.empty`
Renamed `FetchFS.prefixUrl` to `FetchFS.naseUrl` for consistancy with `FetchOptions`
Added optional generic type to `StatsLike`
