Center Lyric Syllables (ignoring punctuation)

When a lot of verses have the same text, but with difference punctuation, e.g. because some verses are in quotation marks, it looks awkward because the text doesn't line up vertically. Even when there is only a single verse, it can look awkward to have the punctuation be included in the width of the syllable when centering it beneath the note. Settings for 'self-alignment-X and lyricMelismaAlignment are respected.

It looks much nicer to center the text of the syllable and then put the punctuation around it.
