#4 Small issue with AbstractMessage

[Jon Woffenden]

Let me start by saying thanks for your hard work on flazr, it's great! I have one small issue, however. I need to create some new Message classes (similar to MetadataAmf0), but I can't because of the getMessageType() method in AbstractMessage. It's only visible from within the com.flazr.rtmp.message package. If you were to mark it "public abstract" rather than just "abstract" then others could create new Message classes without polluting flazr's com.flazr.rtmp.message package.

Could we make that method public abstract, then? I'd really appreciate it!
