By Andy's request, I've removed the window_manager.progress_xxx stuff (so
no longer hijacking the mouse cursor) and instead show the Flamenco status
in the Flamenco Render panel.
This file is saved to '{blendfile}.flamenco.blend', which is used to BAM-
pack and create the Flamenco job. After that, the file is removed from
the local filesystem again.
Lots to do:
- Doesn't call BAM yet to copy files onto the job storage folder (even
though you can configure that folder).
- Uses the same project as Attract, so you have to select it in an
unintuitive location. Also, you can only start Flamenco jobs on a project
that is Attract-enabled (and not necessarily Flamenco-enabled).
