IMHO we should have consistent interface with the rest of gcmd.
Currently we have for all file operations:

        * multiple file selection -> perform action for selection only
        (copy, move, etc.)
        * no selection -> operate on single file under cursor
So we can use the same scheme for the internal viewer: multiple
selection - viewing the selection only (in order as in gcmd file list
pane), and viewing single file otherwise.

Currently internal viewer processes files referenced by their URI names,
we need to change it to use GList of selected files (trivial work). Such
approach will allow also for prefetching into memory next/prev files in
the list, so we can achieve very short viewing time.

The GUI can be also very similar to the gcmd's: the toolbar with
FIRST,PREV,NEXT,LAST buttons and navigating with ALT+LEFT and ALT+RIGHT
(or LEFT and RIGHT).

What about this?
