Fixed splitting bug (really the same issue from stable) in get_pageid_from_url(); upgraded TinyMCE to version 3.0-stable
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."
});
