client.replace docs do not agree with codebase

http://www.couchbase.com/docs/couchbase-sdk-java-1.1/api-reference-summary.html

client.replace arguments are key, expiry, object, but are indicated as key, object, expiry

Not splitting key/value makes more sense as the API will be more consistent in JVM languages that allow default values, e.g. replace(key, object, expiry=0), but the rest of the API uses key, expiry, object order so splitting makes sense to be consistent in the Java version.
