Code cleanup: implement window title update via signal

This seems quite convoluted to me but I can't seem to make a more straight
forward implementation work. The idea is that core code should never
directly call into the UI.

So instead the core code (this is C code) calls a helper function. That
helper function calls a member function of a class which in return emits a
signal. The UI code connects to that signal and acts accordingly when it
is received.
