Extensions to the ABC format

Fluyten generally follows the 2.1 spec for the ABC format with a few extensions:

• !...! notation is case-insensitive (!d.c.! is handled alongside !D.C.!)
• !/!, !//!, !///! or !tremolo!, !////! can be used for tremolos.
• !d.c.alfine!, !d.c.alcoda!, !alcoda!, !d.s.alfine! and !d.s.alcoda! are supported for complex repetition patterns.
• Microtonal notes are supported via ^/ and _/ (instead of ^ or _ accidentals) for quartertones and ^3/2 and _3/2 for three-quartertones.
• !glissando! and !gliss! can be used as a decoration to draw a glissando to the previous note.
• !ped! or !ped(! for pedal down and !ped-up! or !ped)! for pedal up symbols.

Several parts of the ABC spec are not supported: instructions (3.1.17), symbol lines (4.15), redefinable symbols (4.16), typesettings (6.1), macros (9), stylesheet directives (11), HTML special symbols (part of 14.1), etc
