Let the instance decide the components of a download

The scenario no longer sends its components with the download request. The instance strips the download by its own config and sends the components it used with the first chunk. If they differ from the ones the scenario started the download with, because the config changed in between, the scenario restarts the download.

A pending download is now marked with sync_in_progress instead of clearing dirty while spectating, and it is set for every download rather than only when inventories are synced. Uploads are skipped while it is set, so a player who leaves during a download with inventories off no longer uploads their stale state.

SyncComponent names the components in the Lua annotations.
