Add image preffered DPI document setting, use it in Writer, Impress

This adds a "image preferred DPI" document setting, which is used
as a suggestion of the DPI that an image should have in the
document. This is currently used when the image is inserted into
the document (Writer, Impress/Draw) to resize it to the preferred
DPI value.
