Writing out proper data for both export formats now (could potentially be read and reconstructed in pixi)

Refactor AnimatedSkeletonGenerator a bit to pull the Sequence out

Default the "name" param to the name of the .swf file being sent

Pulled in a bunch of skeletal stuff, it probably doesn't work (and it for sure doesn't save the export), but it compiles

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
