--User changes

-Allow for saving EXR as full 31-bit float per component per pixel.
 -Allow for saving the output from the final render dialog as a different image format without starting the rendering process over.

--Code changes:
 -Make StripsRender() handle memsetting the final output image so calling code no longer has to.
 -Make FinalRenderEmberController<T>::SaveCurrentRender() return the path that the image was actually saved to.
