[nautilus/wip/corey/dnd_features: 1/7] list-base: Allow dropping text to create a text file

commit 5dcf877f53ec00fe1f9e0c6671ee2940af141d65

    list-base: Allow dropping text to create a text file
    
    We already have the function in nautilus-files-view-dnd.
    Allow dropping G_TYPE_STRING and call nautilus_files_view_handle_text_drop()
    to generate the filename and create a text file.
    
    This only worked in the main view in previous versions, so lets keep
    that the same for simplicity.
