Dramatically improved the page-rename UX and added a miniPrompt API that allows small pop-down prompts as opposed to prompt() or confirm().
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."
});
