Log Message:
-----------
1. Added export of Blender's lamps as After Effects lights. Type of Blender's lamp is added to name of After Effects light 2. Added option to export static scene. In this case not necessary to go through each frame and refresh context 3. Added several conditions to prevent from adding unnecessary keyframes in After Effects. Values of properties that don't changed are set once and no keyframes are added
