terminal: remap Ctrl+N to call terminalPrivate.openWindow
terminal: remap Ctrl+N to call terminalPrivate.openWindow

It is not possible to use web APIs to open a new tabbed app window.

window.open will open a new tab, or a popup.
chrome.tabs.create will open a new tab
chrome.windows.create will open a normal or popup window, but not app.

The web platform team are talking about adding or extending web APIs to
support this, but until then, we must use a private API.
