Title: Updated ivy.xml to have com.google.protobuf as groupId

In the central maven repo the groupId for protobuf is "com.google.protobuf"
http://repo1.maven.org/maven2/com/google/protobuf/protobuf-java/2.3.0/protobuf-java-2.3.0.pom
This should work, I cannot test fully as protoc not installed on this machine.
