Add ShowDetachTabAction to TabContextMenu::DefaultOptions
I added ShowDetachTabAction to TabContextMenu::DefaultOptions. This exposes the "Detach Tab" item in the tab context menu when more than one tab is open. Without this, as far as I can tell, the item never appears, making it impossible to move tabs to new windows. (I filed a feature request about this, bug 443947.)
