RTCDtlsTransportState definition needs some wording wrt sctp/data channels

[fippo]

nit: the definitions of the connecting and connected state in
http://ortc.org/wp-content/uploads/2015/10/ortc.html#idl-def-RTCDtlsTransportState
focus a little too much on DTLS-SRTP. Needs some wordsmithing for SCTP/data channels.

How about this?

connecting

DTLS is in the process of negotiating a secure connection and verifying the remote fingerprint. Once a secure connection is negotiated (but prior to verification of the remote fingerprint, enabled by calling start()), incoming data can flow through (and media, once DTLS/SRTP key derivation is completed).

connected

DTLS has completed negotiation of a secure connection and verified the remote fingerprint. Outgoing data and media can now flow through.

sgtm, thanks!
