Reformat statistics tab in MainTab tab widget

Rename various labels and text into clear pairs and reflect changes into
.cpp file.

To avoid clashes with names on other tabs use '..All..' to emphasise
that this page deals with an aggregate across the selected dives.

Re-format the statistics tab.

Add various keyboard shortcuts.

Add shortcuts to match GTK version for view menu items and the log menu
so that e.g. Ctrl+1 selects the list view.

Remove debug statements from the view functions. Leave in place for
functions with no obvious actions yet coded.
