Updated README.
Added Flash chat-client sample (not yet finished). Note that this breaks the C++ build because it uses Flash-specific features - perhaps some conditional compilation will be needed.
Added FlashMessageOutput.
Finished the chat client demo.
Added the message definitions for the chat client demo. To do: add the .proto file, and a script for compiling it using ProtoC.
