Convert dynamic marks (given in a <direction> tag, assigned to the staff at a given position in xml, not to a note like in lilypond)
Don't crash when a score does not have an explicit key or clef set (e.g. Rosegarden produces such files).
Also convert '0' in part ids to 'Zero', simplify that code a bit.
Sorting of the parts in the .ly output. Currently, their order was not first staff, second staff, third, etc. but seemingly random
Convert articulations like fermata, staccato, tenuto, tremolo (only single-note tremolo), accents, etc.
Remove Info dir entries correctly in 'make install'
Add a full stop in documentation.
Sorting, formatting, adding punctuation, removing a double entry.
Whitespace and punctuation issues.
