    Fix shell_get_thumbnail* to not be specific for GtkRecentInfo items
    
    Currently function shell_get_thumbnail_for_recent_info located in
    src/shell-global.c is used to get thumbnails for recently used files.
    However, it only works if you have a GtkRecentInfo object for the file,
    even though the thumbnail generation code doesn't depend on it. This commit
    renames the function to shell_get_thumbnail and makes it generic so that it
    just takes two strings: a filename and a mimetype.
