GE Patch by Hamed Zaghaghi - Adding Motion Blur to the Game Engine.

I reviewed the code, suggested an update ( initialising accumulation buffer ), and tested the resulting update successfully.

It's great to see more GE developers!GE Patch by Hamed Zaghaghi to add motion blur to the GE ( using the accumulation buffer ).

I reviewed code and tested, gave some feedback ( initialising accumulation buffer ) which was implemented straight away, and re-reviewed.

It's great to have another GE coder on the team!
