QML UI: another attempt to fix the random crashes

I finally was able to reproduce the crashes with the infinite recursion when
computing a GridLayout.

This seems to be triggered by competing Layout.fillWidth settings that the
layout engine couldn't figure out how to accomodate.

I did three things to make this work better:

- explicitly grab the columnWidth for the width of the DiveDetailsView.
- split the GridLayout in two so the area above and below the profile are no
  longer forced to fit in the same column widths.
- remove most of the Layout.fillWidth settings and only leave a couple that
  seem sufficient to get reasonable on screen layout in my experiments.

Here's hoping that this one is finally resolved.
