It sometimes comes up that the best way to solve some particular problem would be to attach a symbol to a barline (eg, think about the commonly-requested multimeasure repeat symbol). But we don't support symbols on barlines, so you end up settling for attaching to the first note or rest in the bar then moving manually, and this adjustment does not necessarily survicve layout changes. This commit adds direct support for symbols on barlines. Also images, since the code involved is so similar, they are handled here as well. Symbols and images are recorded as child elements, which were already being laid out so no special handling was needed beyond adding & removing, reading nd writing. Although I did need to make sure the track & score were managed correctly.
