Feature request: Paste images or URLs to import from clipboard

[Ian Langworth ☠]

Detailed description of the problem

Imgur allows me to paste an image or URL from clipboard to import it.

With Lychee, I have to click the menu and then "Import from link" for URLs, and there is no paste-from-clipboard support.

Steps to reproduce the issue

Open Lychee. Click the menu, or try Ctrl/Cmd-V to paste.

Output of the diagnostics (Settings => Diagnostics)

Warning: Dropbox import not working. No property for dropboxKey.
No critical problems found. Lychee should work without problems!
