Review request for Okular and Albert Astals Cid.


Description
-------

Recent patches introduced a case (PDF file with existing native annotations and without /Encrypt) in which annotation changes are not saved locally.
This patch turns Okular into a ReadWritePart and checks for such annotation changes in queryClose().

Annotation editing is always disabled if we're loaded as ReadOnlyPart, no matter the document type.
I can change it, if necessary, to prevent annotation editing only in PDF files with existing native annotations and without /Encrypt. I didn't do that because I think that this behavior can be confusing for users.

I added the KParts/ReadWritePart ServiceType only in okular_part.desktop (which only handles .okular archives) so that other apps don't think that we are a real editor for all supported formats.

Testing
-------

It works for me.

Expected result:
- It's possible to edit annotations if we're loaded as ReadWritePart (eg by Okular native shell). If you annotate a PDF file with existing annotations and without /Encrypt, you also get a "Save changes?" prompt if you try to close the document (by pressing Quit, reloading, opening another file, or following a link to another document) and you haven't saved yet.
- It's not possible to edit annotations at all if we're loaded as ReadOnlyPart (eg from Konqueror), not even non-native ones. The relevant GUI items are grayed out.


Thanks,

Fabio D'Urso
