because it was hard to find that ctrl+click selected it,
then a delete button press removed it. it's better now. :)

Make tooltips work in the profile toolbar

This patch enables tooltips on the profile toolbar. Tooltips were
being treated as text to be shown at notification area. Now it is
verified if the cursor was positioned over the toolbar when it
activated the event. If so, tooltip is shown normally.

Fixes #238
