"Replace all" (in search dialog) triggers several "document changed" events in same document

[fedejeanne]

The loop in FindReplaceDialog::replaceAll ends up triggering several events in the same document when doing a "replace all". This is a performance problem because each event ends up iterating and processing all annotations in the document.

See this discussion for more details

@mickaelistria I'm not planning to come back to this issue any time soon (I'm currently working on other stuff). Would it be OK to add the tag "help wanted" here?

Thank you very much.
