Adding support for StartPage.com

[Bazoogle]

I like this, but it does not offer support for startpage.com, my primary search engine preference. I added working functionality to this in tampermonkey, so I took those changes and applied them here as well. This will need testing, as I have not tested these changes in git hub, but I have tested the changes in tampermonkey. You can see the tampermonkey file that I am using here: ChatGPT Search.user.txt

I also added a general error message for any status that isn't 200 so you know it responded with an error code, instead of thinking it's taking a while to respond. That was an issue I ran into.

The only change I did not apply to the git hub version that I did do in the tampermonkey version is I removed the extra spaces at the beginning of the answer. It added 2 \n at the beginning and it did not look good, so I removed them.
