Add support for "kiosk" URL parameter

[satterly]

Go to ... http://local.alerta.io:8000/alerts?kiosk=1

Once logged in, the screen will go to "full screen" mode and the top menu will disappear.

It is giving the above error.

"kiosk" url parameter is passed to API calls
API knows nothing about it (I guess it actually shouldn't) and returns error

I think we should remove this parameter from API call or maybe change the way kiosk mode is enabled?
