Previous to bug 1453751 favicons were loaded from the network by a <xul:image>
tag with validate="never". This caused us to always use any cached version if
possible. Bug 1453751 used a normal load type causing us to revalidate with the
server for each request. This switches the loader to using the cache if possible.
