Change preferences into a notebook and add second page for tec settings

Not sure this is the best naming scheme (General Settings / Tec Settings)
but it's a start.

The idea is to have the settings that a recreational diver might care
about on the first page, and all the other stuff on the second one. Let's
see how this works out long term. For now I moved OTU over and added
toggles for the different partial pressure graphs (only the pO2 one is
implemented so far).
