Fix some prerequisites

[junedev]

We need to add pointers as prerequisite for "elons toys" and "census" now that we have it. (#1724)

Additionally "logs, logs, logs" is missing range-iteration as prerequisite.

Now that functions is available, it should be a prerequisite for "gross store" (functions will replace the current "multiple return values" concept which is currently missing from maps anyway).

An update of both, config.json an design.md if needed would be great.
