This adds a security icon (either secure or insecure) to the portal
helper's title bar. As soon as a part or all of the page and its content
is served insecurely, the icon shown will be a broken padlock.

The title of the window should not be in control of a potentially
hostile hotspot provider, so only set the subtitle to be that of the
page, the main title will stay the same.
The subtitle will also be set to a URI, so that the hotspot cannot be
used to control the title shown in our UI.

Even though the window is maximised when created, the window is still
resizable. This avoids making the window smaller than usable. If the
screen is smaller than the minimum window size, the maximise should make
it fullscreen and non-resizable.

Users are currently experiencing intermittent (and hard to debug) TLS
errors when loading the portal authentication page. This could be
caused by using http://www.gnome.org/ for our connectivity checks
because it redirects to HTTPS.
We can completely remove TLS from the equation by not using HTTPS.
http://nmcheck.gnome.org/ is a good choice because it doesn't redirect
to HTTPS and was created for NetworkManager's connectivity check.

We assumed that either a portal would give us a target URI, or we
would eventually reach the URI of our choice (which is http://www.gnome.org)
This is not always the case: even after a successful login we may
stay in a confirmation page, so make sure that every time we see a
redirect we trigger a connectivity check (or queue one for when
the user closes the window)

Add a small DBus-activated GtkApplication that embeds a WebKitWebView
and implements some minimal logic to see if the login succeeds.
It will try to connect to a custom NM-provided url (the portal login
page), if one exists, or to www.gnome.org in the normal case of
a portal doing redirect.
