Added the ability to login wihtout security token where the ip filtering
authentication method is in use. Created a new constructor for
SalesforceLogin which takes the following params username, password,
organizationId, sandbox=False,sf_version='23.0' and uses slightly
different login soap request.
Enable 2to3 for setuptools installs.
Merge pull request #12 from mayfield/master

Enable 2to3 for setuptools installs.
Added descriptions for the new Salesforce authentication method of IP
Filtering
Use a reusable requests.Session object.

Reusing the same request.Session object provides better performance
for back-to-back queries as it lets urllib3 reuse the same socket when
appropriate.
Fixed a bug where SalesforceLogin was overwritten by a method with the same name and refactored both functions into a
single one to support both IP Filtering and Security Token authentications methods
