audio/fasttracker2: Update to v1.07

Changes since v1.06:

v1.07 - 30.01.2020
- Bugfix: After deleting the very last vol/pan envelope point, the currently
  selected point wouldn't be properly set. This is actually a behavior/bug
  from real FT2, but I wanted to fix it anyway.
- Bugfix: Attempting to add a vol/pan envelope point to a completely empty
  envelope would mess things up. Empty envelopes in an allocated instrument
  shouldn't happen, but it happens when loading certain non-FT2 XMs.
- Bugfix: The envelope plotter could display garbage on envelopes with tick
  offsets above 324. Now it just cuts off at the end instead. Also yes, such
  envelopes can be made! OpenMPT, f.ex., has no 0..324 limit for envelope ticks
  in XM mode.
- Bugfix: A couple of system request dialogs had the wrong button captions.
  (Yes/No instead of OK/Cancel).
- When pressing Esc. and the song is unmodified/saved, you'll now get the
  classic joke quit dialogs from FT2 asking if you really want to quit.
- Some minor optimizations and minor fixups. Nothing to write home about...
- Windows 32-bit: This version now requires your CPU to have the SSE2
  instruction set. Intel CPUs from around 2000 (AMD around 2003) and later
  have it. In other words, it's not worth my time trying to make the clone
  run on such old machines!
