Like what I have done for the historical hex command references, the same should be done for historical MML commands. It'll also help in the conversion process later on for when the user wants to manually adapt older MML files to AddmusicK and there is a syntax that perhaps AddmusicK doesn't quite support yet.
Related to #235.
