Replace logo with platform-dependent button to open app menu (#239)

Replace the logo in the tab bar with an ellipsis icon that shows on
Linux and Windows and, when clicked, opens up the system menus. This
also fixes an issue I noticed where the context menus were set to the
wrong coordinates when a window was zoomed in.
