Fix up a problem with geom and friends when some external thingy moves stuff behind our backs. 

This happens during startup at least and did cause problems.

Restrict image loading to images from the same edje file we are in, as per rasters request.

Some minor cleanups.

This commit fixes the last of the known problems.
So it's ready for release, except for adding docs.
I'll be adding docs over the next week anyway.
