        * shell/ev-application.c, shell/ev-application.h:
        * shell/ev-window.c: Recent files support.

        * configure.ac: Added "ru" to ALL_LINGUAS.

        * dvju: new backend to support DJVU files.
        * dvi: new backend to support DVI.

        * configure.ac, Makefile.am, shell/Makefile.am, ev-window.c:
        * ev-application.c: Support for new backends.
