Revert aa7797145a9ba0340e6dde2a6504cbeadc8294b7 (Hide toolbar in fullscreen windows. Save toolbar setting in user prefs. Make sure it is consistent across all windows.)
Change cmd-t to open new tmux tab if the current tab is tmux, same with cmd-w. Work around bug in tmux not outputing %end for unlink-window.
