Provide means for starting the Qt console maximized and with the menu bar hidden

Not sure if this is exactly the correct approach to using the config, but what I wanted was the option to start the Qt console as mentioned above.
to use:
`IPythonQtConsoleApp.hide_menubar = True`
`IPythonQtConsoleApp.start_maximized = True`

I'm also not sure where should the documentation for these be put.
