Gifski requires at least 2 frames in the resulting GIF, but users might accidentally trim or choose low enough FPS for the resulting GIF to contain less than 2 frames. We should show a warning in the editor's view in that case.

Right now, we just show an error when the conversion starts:

Someone could fork https://github.com/sindresorhus/plash-bing-photo-of-the-day and adapt it for other services.

For example:

• Pexels - Curated photo: https://www.pexels.com/api/documentation/#photos-curated
• Pexels - Search: https://www.pexels.com/api/documentation/#photos-search
• Pixabay - Search: https://pixabay.com/api/docs/#api_search_images

Contributions welcome. Jus

Im just saw you used "directory = " in the spritesheets definitions. However our documentation says this is deprecated. https://www.widelands.org/documentation/animations/ So better to use the animation_directory = again.

I'm sorry, wasn't aware of that. I corrected them for this PR. (but Frisian unit definitions still use directory = a lot)

I think we should validate the text fields and indicate invalid/unsupported input somehow. Maybe making the text field have a red border.
