Logins: if the error message string doesn't look like a langstring id, don't prepend "user_err_" to it (some auth plugins are not localized at all, this lets them be without ugly cosmetic bugs)
tinyMCE.addI18n('en.paste_dlg',{
text_title:"Use CTRL+V on your keyboard to paste the text into the window.",
text_linebreaks:"Keep linebreaks",
word_title:"Use CTRL+V on your keyboard to paste the text into the window."
});
