[OpenLayers-Dev] Patch: NavigationHistory tracks base layer changes

[Jochen Topf]

Hi!

Enclosed a small patch to optionally also track base layer changes in the
NavigationHistory Control. Just set the trackBaseLayerChange option to true.
Default is false, ie. old behaviour.

I use this at http://bestofosm.org/ .
