this still disabled sslv3, but in a more internet explorer friendly way

I had changed both 17 and 18. This PR changed 18 back.

This line reads all protocols except SSLv2 and SSLV3, which basically means use TLSV1, 1.1, and 1.2.  So yes, we want to be using TLSv1 (and higher). Not sure why everyone suggests removing bad protocols, rather than actively adding the good ones.
