Improved event firing of OnDoubleClick and OnClick

* Single click produces one OnClick event
* On a Double Click in produces a OnClick, then a OnDoubleClick
  event. Old behaviour used to procuder yet another OnClick at
  the end. This is not needed.
* OnMouseDown and OnMouseUp events behaviour has not changed.

The reason we introduce the FOnClickPending instead of fully
handling the events in TfpgWidget.MsgMouseUp is because a TfpgButton
has slightly different behavior (eg: When clicking on a button, keep
mouse down, and move mouse out of button rectangle, then an
OnClick must not fire.) The extra FOnClickPending allows us to
toggle this behaviour of HandleLButtonUp (which normally fires
the OnClick event)
