[glade/composite-templates-new: 1/4] Support load and save of files with a <template> element.

commit e6ffc0cc58e610e18c7a18377cac3ba2e677432f
Author: Tristan Van Berkom <tristan van berkom gmail com>
Date:   Sat Mar 30 20:00:52 2013 +0900

    Support load and save of files with a <template> element.
    
    GladeWidget now has a "parent-name" property which specifies
    the class from which a template derives. Loading and Saving
    code now takes <template> tags into account.
    
    A GladeWidget is instanciated slightly differently for a <template>
    (the parent-name class is used for instantiation).
