    width : width,
    theme_advanced_toolbar_location : "top",

    theme_advanced_statusbar_location : "false",
    theme_advanced_link_targets : "_blank",

    relative_urls : false,
    remove_script_host : false

Answer 1

For TinyMCE 4.0.23 you can use the (undocumented) option:

default_link_target:"_blank"

as is:

tinymce.init({
    selector: "textarea.rta",
    auto_focus: rta_auto_focus,
    forced_root_block : false,
    statusbar:  false,
    menubar:    false,
    content_css : "content.min.css",
    plugins: [
        "autolink lists link autoresize",
        "searchreplace code",
        "paste"
    ],
    default_link_target:"_blank",
    toolbar: "undo redo | bold italic underline | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link"
});

Got it resolved with parameter

    extended_valid_elements : "a[href|target=_blank]"
