login.py: SOAP XML response with British pound symbol causes encoding error

[dalefrancum]

While using British pounds for currency, during the SOAP API call to authenticate, a response is returned from Salesforce which contains this line:

<currencySymbol>£</currencySymbol>

The login.py code tried to parse the response with this line:

xml_value = xml.dom.minidom.parseString(response.text)

The following error occurred:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xa3' in position 777: ordinal not in range(128)

I have a proposed fix for this, which is to remove the node from the XML response string. I will post the patch shortly.
