Outdated protobuf version in Anymote Library

[GoogleCodeExporter]

In our app we are using the actual version of protocol buffers (2.4.1).  Adding 
the Anymote Library to integrate some second screen functionality i get a build 
error, resulting from the duplicate protobuf lib in my buildpath.

When i replace the existing protobuf jar (2.2.0) in the Anymote Libray with the 
actual one (2.4.1) i get a NoClassDefFoundError, when i try to pair with gtv:

So it would be nice when the Anymote Library (or rather the integrated Pairing 
Protocol?) could be updated to use the actual protobuf version.

We succeeded in making anymote use protobuf 2.4.1. Here are the steps I did:
* Create new anymote.jar: switch to new protobuf jar, re-compile .proto
* Create new polo.jar: switch to new protobuf jar, re-compile .proto, adjust 
ProtobufWireAdapter.java to use GeneratedMessageLite not GeneratedMessage
* AnymoteSender.java: remove unused onDataList method and unused imports

Seems to work.
