fix multidb handling
Minimal binary protocol support (get/get_bulk/set/set_bulk only).
Support remove/remove_bulk with the binary protocol, making the minimal set of read/insert/delete complete.
Updated README with binary protocol support information.
Removed two not implemented methods that were only actually used by the HTTP transport.
Removed a useless time import, also left over from the HTTP transport implementation.
