FramePacker sort only *remaining* frames to pack, because when we skip the index forward by the number of frames we packed, we won't necessarily be skipping the correct frames (since we skip in the *UN*sorted array). Instead, sort this.frames at the start of FramePacker process

Exporter now packs all graphics on the same FramePacker, and sends all the pngs back (had to up the string length size to 4 bytes for all the data)

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
