* drop python 3.4 support

Our dependencies have started dropping support so it is becoming
difficult to test. Additionally, Python 3.4 represents <2% of our
downloads, so taking on a large maintenance burden to maintain support
isn't a good use of limited time. Accordingly, we're dropping testing
infrastructure and migrating our abi3 wheels to py35+.

* use removed instead of dropped

* Windows Installation: fix link to binaries

While https://github.com/pyca/infra/tree/master/windows/openssl points a trusted source (which would be preferable),
pyca/infra currently does not provide any Windows binaries for download. Linking to the official OpenSSL wiki seems to 
be a reasonable compromise.
