Fix accel leak in task manager and bookmark manager by using

the same cleanup code as browser_window_gtk.

Also fix a leak of the gtk widgets when the accelerator was
not used for the task manager.  If the user closed by using the
window manager destroy, then we never called gtk_widget_destroy
on the window and leaked the widgets.
