Sending commands either via cmd line or stdin (also update .gitignore to ignore *.airi files, since it's easier to just produce those instead of signing an exe if we are using the projector version)

Better command handling and arg parsing from the wrapper

Start a wrapper program, "./exporter.py" which creates a simple socket server, and then starts GraphicExport.exe, which now attempts to find that server in order to accept commands and do console IO. ...

Should work with either the air-runtime-bundled app, or the projector exe.
I only included the projector exe as the air runtime one is a little more heavy-weight.
The downside to the projector exe is that it can't accept cmd line arguments, so we just have to hope that we pick the right default port that exporter.py is using (7890 currently)
