Description

Since all RPC requests/responses are now ProtoBufs, it's easy to add a TRACE level logging output for ProtobufRpcEngine that actually shows the full content of all calls. This is very handy especially when writing/debugging unit tests, but might also be useful to enable at runtime for short periods of time to debug certain production issues.
