[Feature Request] Add support to use url of recipe image instead of attaching a local image

[StuGotz]

When mealie is unable to parse a site for a recipe, I'd like to automate importing an image into the manually created recipe. Currently the workflow requires you to download an image locally to import into the recipe. I'd like to supply a URL of the image to use from the original site to automatically download the image and store it.

I agree! this would be easy, and i assume it would be relatively easy!

This is already supported, just paste the URL in the file open dialog (see example below)

To add, pasting an image from the clipboard would be great, too.

This will be fixed in the next release. Ref #288
