Move some files back to the server "library".
Merge the 'console' lib with server, as it doesn't really make sense with
just one file and nobody exclusively linking to it.
The server "libary" is not really a library, its the place we put all
the files shared by hub-qt hub-cli and hub.
We no longer depend on these files from other places (mostly due to
moving to the new logging framework) and as such we can move the files
back.
The change signifies that the server is not just for admin purposes it
will become the preferred way for all subnet-local interactions.
Notice that we still have the JSON based RPC protocol as fallback.
