Extra spaces in customer class, invoice number, customer number etc

[Thomas Adrian - Consili]

I have customers that have extra spaces in various places in VN. such as customer class , invoiceno and customerno.

I think this is probably caused when importing data or using cut&paste. 

this is a pain when working with the API as the api show these space character as well. and it is easy to forget to trim these fields in code. or even to know which fields need to be trimmed.

please add a validation for import and input and do not allow spaces in these kind of fields. (or trim fields that should not contain spaces in api)
