Benjamin Otte 4a6ecf33fc gtk-demo: Don't use mad mime type guessing 
... for displaying resources. Instead use the proven and way more
reliable method of trial and error.

It's less code and more portable for a start.
But most of all it displays PNM files as text if you fail to compile
the gdk-pixbuf loader for it.
