Marker Below The Overlay Widget - Add support for custom makers

[lulumeimei]

The overlay widget is placed above marker. Cannot see where the marker is.

This unfortunately is the nature of the way this plugin renders - I am currently rendering above the native google map implementation meaning any markers or polylines will be covered by overlaying widgets.

This sadly can not be fixed, sorry!

I could how ever have a look into rendering custom markers in the overlay instead of relying on google maps to do that for us, and will leave this issue open for that potential fix :)
