Vadim Zeitlin e5eff43833 Clear the search control automatically when it's "Cancel" button is pressed.
This should be the desired behaviour in the vast majority of cases, so do it
by default.

Replace the useless OnSearchButton() doing nothing with search button events
with OnCancelButton() handling cancel button events and clearing the control.
