Embeddable links #100
Description
With the web port (#68) it would be nice if I could share examples using a URL that opens an editor/viewer/game showing a custom scene. Metadata could provide a preview screenshot, and a way to download the example (links to the relevant pk3 files).
This is useful when explaining something on a forum, but could also be embedded in the in-game wiki (#88). Examples you can jump right into, all from the comfort of your browser.
You could also pass parameters (such as the model to view) via query arguments.
