The pack hosts itself

• New: the resource pack is uploaded to ResourcePack AI's free pack host by default (pack.host: upload), so players download it with nothing to open or set up, on any host. It is only uploaded again when it changes, and only the Minecraft client can download it.
• A pack over the host's 95 MB is served by your server, as before, and the console says so. A server that set pack.url keeps serving the pack itself; any other moves to the pack host on its own. pack.host: serve keeps it on your server.
