Band Lineup 1.13.0: a photo per instrument, picked by the spot each person is in that week

DJ plays drums one week and sings the next; one photo can't fit both. A
person can now have a photo per instrument, named "Name - Instrument"
("DJ - Drums.jpg", "DJ - Vocals.jpg"), plus a plain "DJ.jpg" for
everything else. Sync reads the instrument family of the spot each person
lands in (its bracketed role, else their PCO position) and picks:

1. the photo picked by hand for them on that instrument;
2. a photo named for that instrument;
3. their everyday pick, else their best-named photo. A photo of them on
   another instrument still beats PCO's headshot.

Families keep the shorthands together: Vox/Vocals/Singer, Keys/Piano/Pad,
Drums/Perc, Bass, Guitar/Electric/Acoustic/Rhythm, Leader. A photo
dropped onto someone is remembered per person per instrument
("<id>|drums"), so a drum pick never overrides the vocal photo. A spot
naming several roles files under its most specific: Leader, then Vocals,
Drums, Keys, Bass, Guitar. Photo names from files now collapse the spaces
left by "Name - Instrument".
