[Soap-Python] Attachments as soap request

[Burak Arslan]

Hi,

First, please update to the latest version of Spyne.

I did not add support for the File type to Soap as the Xml Schema 
standard doesn't have a File primitive. You can have binary data sent 
into Spyne code via SOAP using the ByteArray (==base64binary) type.

By the way, Spyne's MTOM code is not working (doesn't even have tests). 
Patches are welcome :)

Best,
Burak
