history:
[fix] remove light box overlay
+[fix] google cache not displaying properly
[fix] made answer type display original header instead of text
[add] fix answer type display: they are in the styles (post times are present)
[add] clearing experts-exchange cookies and reloading page makes answers visible
[add] remove adInNav height ad placeholder
[add] use google cache
purged:
[add] make page refresh after clearing cookie
this is equivalent to fetching answers using google bot user agent
[fix] check if realAnswers include post types
this will be more recent, even if answer types are not shown
