Replication protocol fixed and response bodies are now not echoing created or modified objects.

Added

• The ?echo query param returns the new/updated object

Changed

• BREAKING: By default, write/update operations no longer return the object (see ?echo)
• BREAKING: Removed :schema, schemas are now added/edited by using the Create Index API.
• Verbosity level 4 or higher (-vvvv) turns on --echo, --pretty and --comments

Fixed

• Replication protocol now properly closing connections on errors
