TreeViewDelegate: allow app to add custom pointer handlers

As it stood, it was not possible to add custom pointer handlers
to a TreeViewDelegate, to e.g do an expandRecursive() if using the
right mouse button, or holding down ctrl during a click.

This patch will change this, so that we only perform the default
collapse/expand operations when using a plain left (double)
click, and ignore the event otherwise.
