Resolve mismatch between data store types and SvelteKit routes

[cuibonobo]

Maybe the page type can hold routing and template information? This would required the ability to render individual Svelte pages if we are given a template. This would eliminate the need to have module blocks on Svelte pages because whatever is building the pages would already have the data.

Fixed with #29 because the data store no longer separates posts by type. Routes are only determined by the Svelte folder structure.
