[JW Lua] Change System Margins after Double barline

[Jari Williamsson]

Herbert et all,

To load a measure number, the construction of the measure object should 
have no parameters, and the Load() method (which you commented out) 
should have a parameter with a measure number. (I now noticed that JW 
Lua will crash if there's no parameter, I'll see if I can fix that.)

So, first replace the 2 first lines that loads the next measure with:
local m = finale.FCMeasure()
m:Load(measure.ItemNo +1)

Second, you also need to remove the line with SaveAll() at the end, 
since it will overwrite the change you made earlier in the script with 
the original data.


Best regards,

Jari Williamsson
