[evince] Evince feature for behaviour when opening multiple documents

[Kimmo Vuorinen <kimmo vuorinen gmail com>]

One thing I would like to see in Evince is that when opening multiple
documents, there would be option not to open multiple windows, but
behave like eog opening pictures.

When selecting multiple documents to open, just open the first one and
have buttons available to move to next/previous document.

This functionality would ease users who have to process large number of
documents, for example accounting people having to seek for information
from electronic invoices.
