Summary	0001926: Since 1.32.* muted channels seems not to be saved in the song
Description	When saving a song which have muted channels with openmpt 1.32.*, they are not properly restored when reopening the song afterward.
Steps To Reproduce	I have done a simple test to confirm this: i created an empty song using openmpt 1.31.05 with 4 channels (i could have used 2... anyway) and muted 3 of thoses channels. Then saved the song. When loading back the song with 1.31.15, the 3 muted channels are still muted. Then tried with both 1.32.01 & 1.32.04. Loading the song, the muted channels are there, no problem. But after saving the song, no channels are muted anymore when reloading it. I have even tried to reopen the song saved with 1.32.* with 1.31.15, and same, muted channels are not anymore.
Tags	No tags attached.

Has the bug occurred in previous versions?	Yes, from 1.32.01
Tested code revision (in case you know it)

Several modules were accidentally spread by their authors (e.g. to sites like ModArchive) with channels muted, while this was not their intention. You can get the old default behaviour back by changing the hidden setting Misc.SaveChannelMuteStatus to 1.
