Ashod Nakashian 8f312862ca leaflet: fire Doc_ModifiedStatus with modified state of the document
When .uno:ModifiedStatus is received, now Doc_ModifiedStatus
is fired to inform the client of the modified state of the document.

This is useful in case the integration needs to prompt the user to save
before closing the document (which they can catch with the onunload or
onbeforeunload events in the browser, as well as with our
UI_Close when the default handler is disabled).

Includes working sample and documentation.

<!-- Proof of concept of running loleaflet.html in an iframe. Also
shows how to, from outside the iframe, invoke Python scripting in
the underlying LibreOffice instance that manipulates the document
being edited.
This demonstrates using the Python InsertText.py and Capitalise.py
scripts from javascript across iframes.
To test this, do 'make run', and then in your browser open the
equivalent of
http://snorken.local:9980/loleaflet/3304e9093/framed.doc.html if the
browser is running on a different machine, or
http://localhost:9980/loleaflet/3304e9093/framed.doc.html if running
on the same machine.
