Couchbase java client ignores provided username and always use bucket as username during HTTP authorization step

new CouchbaseClient(servers, "default", "username", "password") doesn't honor provided username and always use bucket as username during HTTP authorization step.

Outgoing request is:
FINE: sun.net.www.MessageHeader@658f73867 pairs:

{GET /pools HTTP/1.1: null} {Accept: application/json} {user-agent: Couchbase Java Client} {X-memcachekv-Store-Client-Specification-Version: 1.0} {Authorization: Basic ZGVmYXVsdDpwYXNzd29yZA==} {Host: 192.168.1.79:8091} {Connection: keep-alive}

Text value of Authorization header corresponds to "Basic default:password", while it should be "Basic username:password"

Therefore 401 unauthorized response received:
sun.net.www.MessageHeader@92f1bf07 pairs:

{null: HTTP/1.1 401 Unauthorized} {WWW-Authenticate: Basic realm="Couchbase Server Admin / REST"} {Server: Couchbase Server 2.1.0-718-rel-enterprise} {Pragma: no-cache} {Date: Wed, 31 Jul 2013 13:10:21 GMT} {Content-Length: 0} {Cache-Control: no-cache}

The actual bug hides at line #131 of method com.couchbase.client.CouchbaseConnectionFactoryBuilder.buildCouchbaseConnection(final List<URI> baseList, final String bucketName, final String usr, final String pwd), wher usr parameter is not used anyhow and just ignored
