Remove the old pub/sub listener which is no longer used.

Also remove the DocsWithPendingUpdates set, which used to track
docs waiting to be updated. This was necessary incase messages were
missed on the pub/sub channel, so we knew which docs still had pending
updates. However, now we use the BLPOP queue, these updates just sit in
the queue until a consumer comes back to continue consuming them.

2589e2d417 Gracefully return when an op has already been submitted 
It is not a fatal error if an op has already been submitted. We just
need to send an ack back to the client that submitted it and continue.
If we detect a duplicate op, set dup: true on the op and pass it back
to real-time for distributing. The dup: true flag will ensure it only
gets acknowledged to the submitting client, not everyone.

a3847d21d5 Replace UTF-16 surrogate characters with 'replacement character' 
In Javascript, characters are 16-bits wide. It does not understand surrogates as characters.

From Wikipedia (http://en.wikipedia.org/wiki/Plane_(Unicode)#Basic_Multilingual_Plane):
"The High Surrogates (U+D800–U+DBFF) and Low Surrogate (U+DC00–U+DFFF) codes are reserved
for encoding non-BMP characters in UTF-16 by using a pair of 16-bit codes: one High Surrogate
and one Low Surrogate. A single surrogate code point will never be assigned a character.""

The main offender seems to be \uD835 as a stand alone character, which would be the first
16-bit character of a blackboard bold character (http://www.fileformat.info/info/unicode/char/1d400/index.htm).
Something must be going on client side that is screwing up the encoding and splitting the
two 16-bit characters so that \uD835 is standalone.
