DOC export: embed images

Hi,

I don't know if this is a bug (IMO, it is) or "by design", but when I export to a Word DOC, images are not embedded (they seem to be linked, as I noticed from the behaviour and looking into the code of the DOCs), while they are embedded into RTFs and PDFs.

They should be embedded in DOCs as well. Not embedding them defeats the purpose of exporting for offline use.
