Improvements to Linux Disconnect/Continue windows.
* Use GtkDialog instead of GtkWindow - makes the code a lot simpler.
* Improve window layout (add some padding).
* Make ContinueWindow always-on-top, to stop it getting obscured. Not sure if
this is really necessary.
* Set urgency hint on ContinueWindow - makes it throb in the taskbar.
* Modify Hide() methods to destroy the window, to avoid unnecessary
memory-leaking for tests.
* Hide the window when user clicks buttons, for instant feedback. Partially
fixes crbug.com/87467 but not completely (the other window stays around if both
were visible).
* Add virtual destructors (coding-style fix).
