document.createElement() can't accept "strong;" as the element name

The Art_Vector_Belly_EP file is not overwritten by he split script.
Perhaps this art is unused? Anyway fix attributes in it.

This replaces twee print statements with SVG data to make the files
usable for the DOM nodes

1. Repair identation (my python refused to execute them as they were).
2. Teach normilize_svg to remove explicit "style=fill:" attributes from
elements, controlled by color classes like skin, hair, etc.
3. vector_layer_split moved from inserting vars with sigil for SugarCube
to using "data-transformation" attribute.
4. vector_layer_split output for the 'tw' format became an SVG too, but
with special attributes.
