Added additional (optional) subframe argument to RNA API function: scene.set_frame()
This is used to set the current frame to a floating point subframe state between 0.0 and 1.0
added to the integer frame. A main usage for this is retrieving geometry at sub-frame
intervals for use in multi-segment motion blur:

Example:
scene.set_frame(5)
or
scene.set_frame(5, 0.25)
