Write correctly nulled error string in c++ binding if cmd failed
Do not add \n at the end of server-side messages, they should have them anyway

Save sph->src_key and use it when calculating named worker index, since it will be overwritten for blocked events

Added new exec() method which assigns sph->src_key from its parameter
Use round-robin sph->src_key assignment. Added \n back into srw_log class to workaround cocaine messages, which do not contain it.
