[Libreoffice] Review needed - fix for 'wikihelp is not context sensitive'

[Jan Holesovsky]

Hi,

https://bugs.freedesktop.org/show_bug.cgi?id=32338

Can you please review, sign-off and push the attached patch to
libreoffice-3-3?  The root of the problem is that in case of the
built-in help, when a help-id is not referenced there, the code tries to
traverse over the parent windows to find at least something.

In the case of the on-line help, we rather want to directly use that
(potentially missing) help id directly - otherwise we always end up on
the 'main' help page.  [And also we can fix the missing help id in the
wikihelp, without the app recompilation.]

Regards,
Kendy
