Pass in base_dir and out_dir on a per-command basis for stdin processing

Removed all old .as files from the original GraphicExport project, and move everything into a flash/ folder, and then into proper folders inside of that. Also fixed the ./exporter.py script to find the Exporter.exe no matter which folder it's run from, and make sure we include the resource names in both .graphic and .asset styles (and if there's only 1 resource file for an asset, don't append _0000 digits)
