Added tab-based interface to userpage UI. Yes, it is plugin expansible, and yes, it breaks existing plugins that add code to the userpage (but that can be fixed with a "colspan=4")
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."
});
