Preferences: start to port preferences to a more sane design

Our preferences dialog right now is a rather huge dialog
with more than 9 subpages, and all of those pages are programmed
inside of the same class, same methods and all that - which means
that if I change something on the dialog I can break any
other thing quite easily.

The idea of this patch series is to make it harder to break
user settings and the settings dialog.
