TLS spec reference (Editorial)

[Casper Biering]

My observations and recommendations;

Discovery 4.1: Removal of "using TLS", since it's implied by the previous sentence and section 4.

Registration 6: RFC5246 is not clickable, and also missing in section 7.

Basic & Messages: Missing reference to spec and is all without version.
