In the overview panel we now show fees when the transaction is created
by us.
This also makes the comment for 'moved' transactions a burden, so remove
that and clean it up.
For each transaction allow to click on it and show lots of further
details about it.
This also fixes various bugs and adds some basic helper methods in
various places.
The QML is barely functional, getting the right data exposed was the
only goal today.
