It is now posible to flush all the previous saving points in redis.conf by using a save directive with a single empty string argument, like it happens for CONFIG SET save.

AOF fileds in the global server state, and define names, renamed with more consistent names. More work to do.

It is now possible to disable password authentication via CONFIG SET. Thanks to Jan Oberst. This closes issue #171.

Added a configuration directive to allow a user to specify the
permissions to be granted to the Unix socket file.  I followed
the format Pieter and Salvatore discusses in issue #85 (
https://github.com/antirez/redis/issues/85).

INFO commandstats section reset with config resetstat, a new microseconds per call field, and a few other minor things

added noeviction policy to redis maxmemory. ZSCORE removed from the list of commands that can't be called when we are low on memory, this command was added in the past for a stupid error.

Now it is possible to use quoted strings in the redis.conf file accordingly to the sdssplitargs() function capabilities.
