Title: Read from replica

Hi, Alexander!

I have made distributed installation of `cacheops` on my production servers. Configuration is master-slave on top of general RedisDB replication. It looks good for me. At present moment it have been working during several days.

I could divide load between two instances. You can see, red and blue graphs on image below

Early replica was "cold" and used only as fallback (blue line). Now all reads serves by both instances. CPU usage decreased from about 95% at peak to 60% on each servers.

Hope my changes help to solve part of the problem #35. Please check them and accept if you will find them useful.
