html_quote issue

[marclava]

In ResolveUIDAndCaptionFilter.handle_captioned_image, the option:
'caption': newline_to_br(html_quote(caption))
Should be:
'caption': newline_to_br(caption)
Or else apostrophes (and probably other characters transformed by html_quote) are showed as html entities in the captions...

I fixed the issue by monkey-patching handle_captioned_image in my profile package, but that's sub-optimal...
(I won't fork the repo only to submit such a trivial fix)

Thanks for your attention.
