Clip Stacks sorting issues

[timfitzzz]

There are a few issues with the way clip stacks (#2) are sorted.

Sometimes the duration indicator in particular is noticeably wrong vis a vis the first clip shown. The same thing can occur with the other indicators, but is most meaningful wrt the duration.

This is because the sorted value of the stack as a whole is in reference to the value displayed, but the first clip may be presented not because of that value but because of a preferred sort.

Questions to resolve:

• [ ] Should Stack-level badges reflect the displayed clip or the stack as a whole? What is most useful vs least confusing?
  • [ ] DURATION should reflect the displayed clip because it's confusing if it doesn't
  • [x] Should duration be displayed as a range, with the clip-specific indicator displayed on the clip?
  • [ ] VIEWS should reflect the stack total because that's definitely the most useful
  • [ ] TIME should reflect the stack as a whole because that's the most useful
  • [ ] Should time be displayed as a range, with the clip-specific indicator displayed on the clip?

Going to go with a no on the time range for now, but a definite yes on the length range and adding a clip-specific length display to the clip face.
