Avoid features warnings when compiling with scala 2.10
fix implicit warning conversion

scala.Predef.refArrayOps were implicitly used to convert the java Array[Byte]
(as returned by java.nio.ByteBuffer.array()) to scala ArrayOps[Byte].

However, Byte inherit from AnyVal and refArrayOps is bounded to T <: AnyRef

Clear warning by explicitly using Predef.byteArrayOps()
update dependency to cassandra 1.1.10
