Fixed:
#5
Added isAnyRequiredFieldNull method (pull request #7 by ilyazaslavsky)

#6
Database index selection removed from RedisManager.
Now dbIndex selected in connection pool.

Update:
- Jedis dependency to 2.4.2 (now it's compatible with spring-data-redis)
- Commons Pool to Commons Pool 2 (new Jedis uses new commons pool)
- Apache Tomcat to 7.0.52
