Fixes the Marko icon sitting on top of the title on the first screen of iPhone Duo. If you opened the More menu before a page finished loading, Read Aloud could stay grayed out. It now works as soon as the page is ready. Summarize and Ask now show math as plain text, like O(n²), instead of raw TeX.
