[Soap-Python] XMLAttribute ignored in ClassModelBase.from_xml()

[Tsah Zelenka]

Hello,

It seem that if a complexType is send to soaplib its attributes are not
processed. In from_xml(), the method has a main loop itering over
the xml element's childrens and ignore the attributes. Here is a small
fix, with limited support for integer/long attributes :
