Exporter.fla now grabs sprite-style frames and packs them to sheets (no return data yet)

Debug mode for DebugExporter.fla (run the fla first, then connect to it as many times as you want with exporter.py) and random exporter fixes

Proper interaction with the exporter now using the new format

Working sending base64 over the json channel to load a MovieClip source in the Exporter.fla

Sending messages properly back and forth using the new driver architecture, and a proper message queue+program completion

exporter.py as more of a driver program, doing all file IO. Exporter.fla as the new flash component
