Crashes on valid scale file

[infojunkie]

Thanks for a useful tool!

I am noticing that the Python script crashes on valid SCL files. For example, exporting a Scala file from the Ableton Tuning site yields a valid file, as per the SCL spec, but the script complains:

Traceback (most recent call last):
  File "/home/kratib/src/music/scala2mts/scala2mts.py", line 143, in <module>
    scala_notes.pop(0)
IndexError: pop from empty list

In the script, I am seeing 2 occurrences of this condition: if line.startswith(" ") but reading the spec above, I am pretty sure the leading space is not required.
