Rename liveblog.EntryView.delete to fix IE8 bug

Old versions of IE didn't like having a method named after a reserved
word - changed liveblog.EntryView.delete to liveblog.EntryView.destroy
to fix this.
IE8 liveblog avatar display fix

Avatar wasn't displaying on IE8 because the surrounding span didn't have
layout. Assign same dimensions as contained image.
Fix IE XHR latest timestamp bug

In the event that the same XHR request gets sent twice (mainly on
scroll), IE tends to just reply with a 304 status (not modified) and
doesn't supply a new response date which throws off the entire
calculation system. In such cases we now default to the previous known
server time.
