Move the NDN object from ndnProtocolService to NdnProtocolInfo.
Fix bug: peekTypeAndVal should be a prototype member, not static.
In ContentObject.from_ccnb, allow content to be null.
Changed informational log messages to LOG>4.
In ContentClosure.upcall, move calling setConnectedNdnHub until after we get the desired content object.
In NDN Toolbar, added Set button to set the hub.
Changed primary connection log messages to LOG>0.
Correct comments for readBinaryElement and readBlob.
In readBinaryElement, added argument allowNull, and use for ContentObject content.
This fixes some of the connection problems where the initial response from a new hub would not decode.
