Summary0001992: In IT files the "mute" setting of channels isn't saved
Description

The default panning value of a channel also says whether the channel is mute or not (if bit 7 is set, it is muted). OpenMPT can read this setting correctly when loading files, but it doesn't save it. I've been able to create a simple test file that has the right bit set to 1 (by using a hex editor).

Steps To Reproduce
  1. Load the attached file.
  2. Check the "mute" setting of channel 3. It should be set.
  3. Save the file.
  4. Load the file again.
  5. Check the "mute" setting of channel 3. It should be unset.
