- Python console argument '--python-console', option so you can start blender and drop into a python console, (useful for debugging some problems on a renderfarm over ssh)

- Also made it so sys.stdin isnt overwritten anymore, instead the interactive consoel overwrites while it executes and restores after.

- removed hope folder from sphinx patch path
