Crash on curvature

>python crt_pi_configs.py mame2003 curvature
Traceback (most recent call last):
  File "crt_pi_configs.py", line 209, in <module>
    generateConfigs(sys.argv[1], sys.argv[2], sys.argv[3])
IndexError: list index out of range

I think I broke this during a refactor. Easy fix.

That's been there since I started looking at the code. I thought it was a 'feature' that a value needed to be added after 'curvature' in order to pad the variables list. :-/
