feat(core,app,android,ios): quality badges from file names

Release names say what their files are — 2160p, HDR, 10-bit, Dual-Audio —
and nothing showed it. naming::quality reads those words, whatever they
are separated by, and Title::quality keeps what more than half a title's
files state, so one odd special does not mark a show down. The facts line
of a title's page ends with them: 4K, 1080p, HDR, 10-bit, Dual audio.
Release groups' names are never read.
