Sensor graph compiler's script format broken for array config variables

[anwu]

Looks like the script format for the sensor graph compiler doesn't work when setting config variables that are arrays. It works just fine when using the snippet format.

C:\Arch\coretools\iotilesensorgraph\test\sensor_graphs> iotile-sgcompile .\basic_config.sgf -f script -o test
Traceback (most recent call last):

I believe the lib_controller proxy has a correct implementation on decoding the array variables.
