common_gui needs extra paraenthesis

[wcole3]

Just a missing set of parenthesis in common_gui.py line 108 for isdigit. If you have an older config file, you can get an error loading it due to the old noise offset default value being noise_offset=''

If you encounter an error like you can manually change the noise offset value to a 0.

I will try to fix that at load time, thanks for reporting.

The latest code in master should now have the fix. Thanks!
