Fix menubar/titlebar-less Standalone window issue in El Capitan
Fix menubar/titlebar-less Standalone window issue in El Capitan

If Standalone is closed in full-screen mode in 10.11, 'sizemode' on the main
window is persisted as 'fullscreen'. On reopen, the window doesn't go into
full-screen mode, but it still lacks menubar or titlebar. This patch forces the
window into 'normal' mode if it was left in 'fullscreen'.

(Firefox appears to ignore 'fullscreen' without actually changing the value,
but I didn't find the code that handles that.)
