Properly show/hide the 'read full article' links when using +/- buttons.
Don't show the homepage icon if there is no homepage link specified by the feed.
Add ability to toggle all images on/off in feed preview. When all articles are expanded, can make scanning/reading easier for some feeds.
Don't display any date if it's not in a parsable format (typical with RDF feeds, but also some RSS/Atom feeds).
Change Homepage icon to something perhaps a bit more recognisable.
Acknowledge jFeed on the in-browser preview page.
Miscellaneous code/whitespace cleanups, extension builder version bump, delete old icon.
