Search pages

Allows searching of pages (both instant and full search).

If you feel like pages are missing; feel free to add! Search looks at:
*value field (value occurs in query -> hit!)
*tags (tag occurring in query, OR query being a substring starting at index 0 of tag)

Searchable pages + tags must be added to the JSON file first!
