Rebuild: NZBs from the chunk store, and a catalog search

lib/nzb (buildNzb, parseNzb) from the current app; NzbService builds a
release's NZB from its chunks; GET /api/v1/releases?q= (every word of the
name) and GET /api/v1/releases/:id/nzb behind the api guard. A test stores
a batch, finds the release and reads its NZB back.
