Automatic HTTP decompression should be enabled

[emilast]

The Adobe blog does currently not work since the HTTP content is received gzip encoded and FeedReader does not decode it:

Example:

https://theblog.adobe.com/news/feed

Error:

System.Xml.XmlException: Data at the root level is invalid. Line 1, position 1.

This fix is simple, I'll create a PR for it shortly.
