Adapted the URI-template to code host console output to correspond to the new URI on the server side.
Added (out-commented) staradmin configuration that allows us to easily turn on tracing written to the console.
Added new assembly references to the staradmin to be able to work with the new typed JSON data that is pushed from the admin server on console output broadcasting.
Adapted the CodeHostConsole class in staradmin to work with the new data- and message format over web sockets, as dictated by the new server side implementation of console output broadcasting.
Merge branch 'develop' of https://github.com/Starcounter/Starcounter into issue/1675
Changed how the websocket handshake is implemented in staradmin when running as a code host console (we no longer send a handshake message back once we receive the upgrade from the server).
Disabled automatic pinging from staradmin when running as a code host console, since the websocket server side currently handles it by closing the connection.
Merge branch 'issue/1675' into develop. Fixes #1675.
