[glom] examples: Add a static image item to the Project Manager example.

commit 0a9fccb4d16bd0f0032c4a6ae92c46c4f6200b54
Author: Murray Cumming <murrayc murrayc com>
Date:   Sun Nov 11 18:41:01 2012 +0100

    examples: Add a static image item to the Project Manager example.
    
            * examples/example_project_manager.glom: This is just so we
    use this layout item somewhere, so we can test it.
            * glom/glom_document.dtd: Mention the layout_item_image tag.
    * configure.ac:
    * Makefile_tests.am:
    * tests/test_document_load_image.cc: Add a new test for this
    feature, using GdkPixbufLoader to check that we can interpret
    the data as an image.
