content: division list fixes and thingies

- drop unused unfinished slots code for divided flash lsit
- tidy and fix guarding against empty divide-by list
- support underOther list in flash list ("other flashes")
- change condition for using flat list (non-divided)
  - used to be if there's nothing to divide by
  - now it's if there's nothing divided into any of those
  - this goes for divided track list too
