minor fix to RubyRedis about bulk commands sent without arguments

Warns if using the default config

Issue with redis-client used in scripts solved, now to check if the latest argument must come from standard input we do not check that stdin is or not a tty but the command arity

RubyRedis: now sets are returned as arrays again, and not as Set objects

SLAVEOF command documented

SLAVEOF command implemented for replication remote control

Fix: no connection timeout for the master!

replication slave timeout when receiving the initial bulk data set to 3600 seconds, now that replication is non-blocking the server must save the db before to start the async replication and this can take a lot of time with huge datasets

README tutorial now reflects the new proto

critical bug about glueoutputbuffers=yes fixed. Under load and with pipelining and clients disconnecting on the middle of the chat with the server, Redis could block. Now it's ok

TTL command doc added

TTL command implemented

S*STORE now return the cardinality of the resulting set

rubyredis more compatible with Redis-rb

minor indentation fix

timeout support and Redis-rb compatibility aliases implemented in RubyRedis

RubyRedis info postprocessor rewritten in a more functional way

dead code removed from RubyRedis

command postprocessing implemented into RubyRedis

Split out EM.attach into EM.watch, add EM::Connection#notify_readable= and EM::Connection#notify_readable?

Allow EM.bind_connect(1.1.1.1, nil, ...) to bind with given address and any port

Fix docs for EM::connect and EM::bind_connect

fixes for latest sequel

retry on deadlocks
