Fixed Blender importer to work with Blender 2.60, add option for importing workers or non-worker models.
Fixed more examples to use worker-less format. All examples should work now.
Only Max exporter should be left to change.
Problem was having too many concurrent workers opened at once. Garbage collection apparently works very slowly on workers. Solution was to close them manually, after model data is sent to main thread.
Also some progress with Blender scene exporter. Some scenes now export correctly, though monkey test scene got worse, even with less hacky code.
