A distributed Studio pack lands in your content folder

• New: a pack bound with /rp distribute is now put in content/studio-<pack>/ and built into RP Engine's own pack, so you can see its files, it sits alongside your own content, and players download one pack instead of two. Each time you publish again in Studio the folder is replaced within a minute; files you changed in it by hand are copied to plugins/RPEngine/studio-backups/ first. See On your server.
• New: /rp distribute off --keep unbinds the server and keeps the pack's folder as your own content. Plain /rp distribute off now also removes the folder.
• New: distribution.mode: cdn in config.yml keeps the old behaviour, where each player is sent the published pack on its own, built for their version.
• /rp edit on a studio: id now links to the pack in Studio, where it is changed, rather than refusing.
