audio/fasttracker2: Update to v1.14

Changes since v1.13:

v1.14 - 22.03.2020
- Bugfix: The Repeat/Replen. numbers in Smp. Ed. would not show the correct
  values for non-looping samples. It should always show the values even if the
  loop is disabled. This caused some strange visual bugs...
- Bugfix: Changing sample numbers on the white piano keys in Instr. Ed. was
  semi-broken (it would show wrong numbers until you changed to another instr.
  and back).
- Bugfix: If you set the current sample to 0E and scrolled down with the mouse
  wheel, the sample list would overflow.
- All bitmaps are now present as 4-bit (+ 1x 8-bit) RLE-compressed .bmp files,
  and are included in the binary as such. This makes it slightly easier to
  edit/add graphics.
