Save default units using GConf

That seems to be the gtk2 way.  Whatever.  diveclog ends up defaulting
to metric units, because we all know that's the right thing to do.
However, I learnt to dive in the US, so I'm used to seeing psi and feet.

So despite the sane defaults, I want diveclog to use the broken imperial
units for me.
