Title: Replaces IConnectionIdGenerator with IConnectionIdPrefixGenerator

Fixes Issue #693

Connection ids need to be unique. Replacing IConnectionIdGenerator with
IConnectionIdPrefixGenerator allows ProcessNegotiationRequest which generates
the connection ids to always append a guid to the result of the generator
preventing bugs resulting from the reuse of connection ids.
