and CFMetaData.cfId to Integer

-----------------------------------
Integrated in Cassandra #485 (See [http://hudson.zones.apache.org/hudson/job/Cassandra/485/])

> The column family id is boxed and unboxed so many times it should be somewhat faster to just pass around the same Integer. Memory won't fill up with Integers.
> The following patch sets type of ColumnFamily.id and CFMetaData.cfId to Integer and includes some obvious auto-boxing optimizations.
