Tentative improvements to highlight plugin problems

Browse Source 
We now use highlight.js in raw HTML mode on the server, rather than
trying to use it with the fakedom. This causes problems with fakedoms
inability to get textContent for a node that has been created by
assigning innerHTML. So we extend the fakedom to allow the original
text content to be saved.

See #2778 for discussion.
