Patch for document type handling

I had a go at cleaning up Evince's document type handling code, and it's
not yet ready to commit, but I wanted to get feedback...

So attached is a dump of my current diff against CVS: not especially
clean right now :-)

I created new files: shell/ev-document-types.[ch]

This handles the logic for looking up a mimetype and getting the
corresponding backend (if any); it gets used by shell/ev-window.c to
handle file opening, and by the Nautilus thumbnailer (not yet tested) -
so that in theory the thumbnailer should be able to work for any backend
for which the thumbnailing interface is implemented.

Since this is shared between evince and the thumbnailer, I created a new
library: shell/libevbackendfactory.la

Unfortunately by autotool-fu is weak; I couldn't persuade
automake/libtool to have a shared library linking to shared libraries
for the backends.  So right now the patch makes everything statically
linked (ugh)

Is this the right direction to go in?

I also had to turn off the recent document saving; it was locking up
evince for some reason.  

There are also some warning fixes in the DVI code (where did this code
come from?  shouldn't we simply link to a separate library?)
