This connects the new feed processor to Zotero's existing feed reader. The new
feed processor assumes a content window environment, so a sandbox in a parent
window is used to load it.
This adds extra tests to check parsing behavior such as entities, tag handling,
CDATA, etc. This will help ensure the new feed processor matches the previous
behavior.
Use Atom namespace when getting fields, and use `<updated>` date before
`<published>`. (The dates are also available on the nsIFeedContainer
(`feedEntry`), but we're getting them directly from the fields for some
reason.)
