Wrong jar included in release

[jsotuyod]

The release uploaded for 0.0.1 includes the correct code, but a jar generated with outdated sources.

In particular, the jar included in the release does not include the fixes to Protocol.java to prevent invalid codepoints. This can be easily asserted, just include the jar as-in in any given project, send 128 messages, and Pomelo will thrown an IllegalArgumentException when trying to perform Character.toChars(-128)

Using ant jar to regenerate the jar and using that new one works just fine.
