v0.28.4

Changed

• Android buttons change only when something real happened; the press
  animation of 0.28.3 is gone. A button that started a job (a model
  download, Test TV, an AI test, an import, saving the log) stays blue
  and disabled with the job's progress as its label until the job ends,
  so it cannot be pressed twice; then green with a tick or red with a
  cross, and the label the outcome calls for.

Fixed

• Model downloads can no longer leave a short file installed as if it
  were whole. The bytes go to a .part file with the expected size kept
  beside it; a download that stops short is an error saying how far it
  got, the button reads Resume with the percentage, and the next press
  continues from there. Only a part of exactly the expected size is moved
  into place, and a model counts as installed only when every byte is
  there. The speech model is unpacked into a folder of its own and moved
  into place whole. Delete partial model downloads in the ⋮ menu throws a
  stopped download away.
