Feed generation has multiple errors

[fuzzy76]

The ATOM feed for my comics (https://server/my/feed/?key=123456789abcdef )is invalid in multiple ways:

1. ID for each entry must be a full URL - it is currently not.
2. Titles are not escaped so a comic like "Jesus & Mo" should be output like Jesus & Mo, but is not. This is a breaking error.
3. The element in the header does not match protocol (HTTP vs HTTPS) in all cases, causing invalid feed.

This is submitted based on what I observe at comics.io – I assume it is running the latest version of the software. I recommend validating the feed with https://validator.w3.org/feed/

Please? This has completely broken the RSS consumption for me, as my RSS reader (Feedbin) is not able to parse the feed.
