Current version number

The CHANGES.md in the current repository mentions 3.5.41 as current 
version, but PyPI has only 3.5.34.

Since you're using Travis already, you should consider adding automatic 
PyPI deployment: docs.travis-ci.com/user/deployment/pypi/

Also, the current setup.py sets __version__ = '3.5.25', while 
src/reportlab/__init__.py sets __version__ = '3.5.41'. I think that 
duplicate __version__ in setup.yp should be removed because it is 
confusing when you forget to update it and it is not used anyway. At 
first I believed to have downloaded the wrong version.
