Version 0.6.0

This version adds rudimentary FBX export capability.
At present the exporter only exports to .\resources\export, so be sure to move the files from one map before exporting another if you don't want things getting mixed up. I hope to improve this in the next version.
Also there seems to be a slight memory leak in the exporter so if you want to export lots of maps I suggest restarting the viewer every so often.
