Reviewed octree filling times... found a way to optimize some 10% of time,
nothing radical. :)
Just remember to always try higher octree resolutions (256 or 512) or more
complex scenes. Can be 5-10 times faster.

For waiting pleasure; added a per-second header print update to tell where
octree is. Also added an ESC test in octree making.

(Commit in image.c is a faulty print for 'Not an anim').
