Adds support for website APIs both complex and simple. This commit
only supports GET requests to APIs. POST request support can be added
on request.
Client IDs and secrets are also supported. They can be added via
source settings or automatically set by a website endpoint.
Also fetch sources for scraping using the backgroundContext and remove
some functions from using the main actor.

RSS parsing has been added as a method to parse source since they're
easier on the website's end to parse.
Source settings have been added. The only current setting is the fetch
mode which selects which parser/scraper to use. By default, if an RSS
parser is found, it's selected.
A source now has info shown regarding versioning and authorship. A source
list's repository name and author string are now required.
