Remove update 'flicker' when tab selected

Browse Source 
The recent patch to reduce redraws when rides are selected
causes each tab to redraw whenever the tab IS selected. This
patch reduces this by remembering the current ride plotted.

It also fixes the "double draw" in GoogleMapControl and AllPlot
when selected for the first time.
