Improve editor support for SA

[DeadMG]

TL;DR

Make it quick and easy to go to space or other planets with /editor.

What?

In the Surfaces tab in the editor, add a "create platform" button that instantly spawns a platform. Additionally, add a button that can teleport that platform to any location. Finally, add a button that forcibly creates the planet's surface so the player can simply go there directly.

Why?

Currently it's a pretty tedious process if you want to mess around/sandbox on the other planets. The only way to get them to spawn is to force research the technology and then actually go there with a platform you manually build that actually goes there.
