Add parser flags

[KungFuFurby]

You know, #amm, #am4 and #amk are all presets in some way, and because of substitution conflicts caused by me partially implementing #1 for music, I think I need to correct that now.

These flags are going to allow me to soft-code some of the features that past parser versions have, and they are user overwritable. They currently cannot help with hex command conversions, though: that's a whole other kettle of worms. Some of these flags will have to be option directives due to not being compatible with being modified in the middle of a song.

Also, most flags can be defined in the middle of a song. The exception is preprocessreplacement.

The list of flags I can think of at the moment...

• preprocessreplacement (would be intended for Possible substitition failure between AddmusicM and AddmusicK #238, must be handled during preprocessing. Enabled by default when using AddmusicM)
• exactdefaultlengthmods (required to implement Adding dotted notes, = lengths and tie support to l directives #1 without substitution conflicts or incrementing the parser version, as 3 is reserved for AMK 1.1.0 beta. This is also the most important one to implement, as without this, AMK 1.0.9 cannot be released in its current state)
• noexactdefaultlengthmods (Undoes exactdefaultlengthmods.)
• forcepercpitchmodonsfxch (Allows Percussion-related notes are always using fixed pitches by mistake in Addmusic405 ports on #6 and #7 in the MML #198 to be freely utilized by others. Enabled by default when using AddmusicM and Addmusic405)
• nopercpitchmodonsfxch (Undoes forcepercpitchmodonsfxch.)
• forcepercpitchmodon (Allows Percussion-related notes are always using fixed pitches by mistake in Addmusic405 ports on #6 and #7 in the MML #198 to be freely utilized by others. This also works across all channels. Enabled by default when using AddmusicM and Addmusic405)
• nopercpitchmodon (Undoes forcepercpitchmodon.)
• no@percgen (Causes the percussion instrument IDs and notes to not generate a percussion note: instead, they always generate an instrument ID and a normal note. May require the cooperation of Have $DA xx account for alignment when referring to percussion instruments #132 to get the job done. Renders forcepercpitchmodonsfxch and nopercpitchmodonsfxch redundant.)
• perc@gen (Undoes no@percgen.)
• rewind& (Allows & is not being properly converted from Addmusic405 #201 to be freely utilized by others. Enabled by default when using AddmusicM and Addmusic405)
• norewind& (Undoes rewind&.)
• ignoretuning (Bypasses hard-coded tuning on built-in instrument IDs... but could also affect future global cases, as it affects Make hard-coded instrument auto-transposition optional (add an optional h setting to instruments) #153, which aims for soft-coded tuning. Not an exact match to Addmusic405's handling...)
• noignoretuning (Undoes ignoretuning.)
• noquantautogen (Disables automatically generating quantization. Most notably affects labels. Would implement a part of Add an option to bypass adding quantization and/or duration info at the start of label loops ($E9 VCMD) #217.)
• quantautogen (Undoes noquantautogen.)
• noloopdurautogen (Disables automatically generating note durations inside of loops if one is not defined beforehand. This also directly affects ties: they won't be auto-merged when this happens due to an edge case that would involve leaving these completely undefined. Would implement a part of Add an option to bypass adding quantization and/or duration info at the start of label loops ($E9 VCMD) #217.)
• loopdurautogen (Undoes noloopdurautogen.)

Just read https://www.smwcentral.net/?p=viewthread&t=98157. Is it worth adding a flag to have percussion always generate percussion notes without having to switch to a percussion instrument once per note?

Actually, that's not a bad idea... kind of like nopercpitchmodonsfxch, except across all channels. I'll add that to my list.
