[Bf-python] Support for a primitive progress bar is available

[Dan Eicher]

HI,

It seems odd it's mapped [0, 9999] instead of something that's a direct
representation of a percentage -- either [0.0, 1.0] or [0, 99] -- since you
most likely have to do a percentage calculation to figure out the progress
anyway.

progress_update(items_finished/total_items)

vs.

progress_update((items_finished/total_items)*1000)
