Coral and WebArchive updates

[Dr-Flay]

Very sadly Coral CDN is no longer running so should be removed.
To make it worth while doing an update, here is a useful addition.
The Web Archive have another system for access via "Distributed Web"
https://dweb.archive.org or https://dweb.me

There are more caches you may want to add such as Bing, Yahoo, Yandex and Baidu.

Thank you @Dr-Flay for the improvement suggestions. I'll make sure to tag this issue in the next release

I look forward to testing the update, when you have the time to work on it.
