Really the eye creature is only useful for me as a debugging tool, so this moves it over to a separate debug page.
It also removes the whole concept of randomizing the eye creature, mainly because it ignores all the rules set forth in the normal creature randomizer, so it's not terribly useful.
This simplifies the code for `creature-page.tsx` a bunch and hopefully makes it easier to understand.
This adds an extremely simple Mandala page (for #24) with a single circle Mandala comprised of several eyes. The symbol style is configurable, but parameters for the actual Mandala are not (yet).
Doing this also involved factoring out a `<SvgTransforms>` component, which makes setting up SVG transforms a bit easier.
Also moved `getSymbol` of `creature-page.tsx` and into `svg-vocabulary.tsx`, with the new name `getSvgSymbol`.
This auto-detects the direction of normals on which to attach attachments.
Right now it's getting very confused by corners, but otherwise it seems to mostly work.
