OpenWebRTC returns the same priority number multiple times

When getting ICE candidates on a data session (not sure if its specific to data sessions), candidates with the same IP vs. different methods use the same priority number. This is a violation of RFC 5245, section 4.1.2.1.

To quote:
More generally, if there are multiple candidates for a
particular component for a particular media stream that have the same
type, the local preference MUST be unique for each one.

Firefox catches this and throws an ICE error, and only accepts the first candidate it got with a given priority (according to about:webrtc). As for Chrome; it appears to not care.
