Setting for default value for "unformat" when the input is invalid / none / blank?

[hllau]

Is there any way I can set the default value, when the input is NaN? At the moment, it spit out "0" which may not be desired all the time.

Pull request #122 should fix this. Is takes in an 'invalid value' parameter.

accounting.unformat('what', ',' , null) = null
