Add support for more search engines

[eat-your-glory]

Hello! I added support for more search engines. Here are the search engines I added support for:

• Kagi
• Startpage
• Brave Search
• Qwant
• Ecosia

Thank you for the contribution! Unfortunately, many of these engines do not work as intended - please either fix or remove the affected entries.

I have removed the Qwant search engine as that was the only one that doesn't work as intended. The only other search engine that you might see doesn't work is Kagi however, Kagi is a paid only search engine so you need to be logged in for it to work. I think Kagi should be included in the search engine list, but I also do think it should be made clear you need to be logged in/its a paid search engine. How should we make that clear?

As of right now, I am not willing to add a search engine that I cannot test to a project that I maintain. As Kagi is a paid service that I do not plan on subscribing to, I cannot ensure the quality of the search results.

As for the other engines, please see the appropriate review comments. Many of them return results, but not correct/meaningful ones.

Apologies for the extended delay - I finally got some free time to review your feedback and it looks all good to me.

Thank you so much for your contribution and for taking the time to help me confirm the functionality of each new engine! ❤️
