Version 4.2 - Bug fix release

This is a release that adds a workaround to a recent update where Valve started putting strings as attribute values. I don't know how to handle this at the moment without a major release and making people change code so for the moment it will merely return 0 for these attributes. Which are currently for custom names and descriptions. Information already available via item.custom_name and item.custom_description.

An employee has told me that this is intentional. So I suppose the bug is steamodd's.
