[JW Lua] Suggestion for the iterator: smartshape filter

[Jan Angermüller]

Jari,

here's a suggestion for the smartshape iterator:
instead of browsing all smartshapes, I would a prefer a filter for 
hairpins, slurs, customlines, etc. that also implements the logical 
method as used in the other filters. Something like:
AddSmartShapeFilter(int filter, int logicmode)

Best,
Jan
