SCENE_RELEASE only for a track post's lower-case name

7ad4b70 also keyed rar uploads by artist and total: "VA - Best Of Shamania
Pro 2K16-(SHB 006)-WEB-2016-ZzZz" became 140 files for 20, Ace_Of_Base 72
for 12. Those group by their full name; only a name without capitals or
spaces (Meow's "blaise_mc-in_hellstill_3-ep-web-2022-known.par2") joins
the tracks.
