patchgit-gui blame: prevent tool tips from sticking around after Command-Tab

> On Mac, tooltips are not automatically removed when a window loses
> focus. Furthermore, mouse-move events are only dispatched to the active
> window, which means that if we Command-tab to another application while
> a tool tip is showing, the tool tip will stay there forever (in front of
> other applications). So we must hide it manually when we lose focus.
