some refactoring
* wrapped ace into a ruby class Harpnotes::TextPane

we now keep the abc in local store. It no longer gets lost if we leave the page
killed an out of bounds bug
optimized display of parts
changed the strategy for jump line vertical part

Improved annotations and legend
now we can process %%%%hn.print {"t":"all",         "v":[1,2,3,4], "s": [[1,2],[3,4]], "f":[1,3], "j":[1]}

The options are passed to the song and from there to the layout engine
