Move space platform request to the schedule part

[h.q.droid]

I just thought of a good solution to the inflexibility of space platform requests: instead of a centralized section like in a requester chest, make requests a schedule clause. An example way to do so is to rewrite the current "Request satisfied for XXX" as "Request XXX * NNN" with a "wait for satisfication" checkbox.

This single change has several benefits:

- Removes the need for an "import from planet" icon and the UI confusion when importing the same thing from multiple planets.
- Enables prioritized loading by going to the same planet several times. For example, a promethium hauler may want to ensure there are enough quantum processors before loading eggs.
- Enables stationary "phases" for manufacturing platforms. Like a quantum processor maker may want to stay above Vulcanus for the free solar power, but right now if it keeps consuming tungsten carbide it may never finish loading it.
- Enables signal-controlled loading with interrupts, while also reading hub contents.

Sounds like a good idea. Only things I'd like to note are the following:
What would the request clause do (other than requesting) if the wait for satisfaction checkbox was unticked?
And how would request groups be synced between platforms if there aren't any request groups anymore?

What would the request clause do (other than requesting) if the wait for satisfaction checkbox was unticked?

It should use the current behavior: the planet prepares the requested things to its best effort, e.g. bot-move stuff to rocket silos. But the platform doesn't wait for it and could leave before finishing loading.

And how would request groups be synced between platforms if there aren't any request groups anymore?

Good question. I guess there could be "schedule groups instead"? A way to reuse platform stops / interrupts by name.
