The backtrace view expects that there is always a valid selection. This
is not true when we execute a step in the debugger. Therefore we need
to check if we have a valid selection in the on_selection_change
handler.
Since the introduction of multi-select, we have had both `on_selection`
and `on_selection_change`, the latter of which was only invoked when a
change in selection came in through the model.
This removes `AbstractView::on_selection` and replaces it usage with
the more explicit `on_selection_change` everywhere.

We can now add a watchpoint to a variable by right clicking on it
in the variable view, and selecting add watchpoint. To remove a
watchpoint, the exact same action is repeated, except it will now say
remove watchpoint.
I hereby declare these to be full nouns that we don't split,
neither by space, nor by underscore:
- Breadcrumbbar
- Coolbar
- Menubar
- Progressbar
- Scrollbar
- Statusbar
- Taskbar
- Toolbar
This patch makes everything consistent by replacing every other variant
of these with the proper one. :^)
