[JW Lua] eachentrysaved can automatically remove the TieBackwards flag

[Robert Patterson]

On further reflection, I think what I'll do is modify FCNoteEntryCell:Save
not to actually save an empty frame when the measure already lacks a frame
for that layer. That will work with any loadlayer mode and not require any
external code changes.
