ResetTool() for GmapPlot centers on lat, lon = (0,0), rather than the lat, lon defined in GMapOptions.

@brendancol could you take a look at this?

As of 0.11.1, reset just appears to do nothing, rather than resetting to 0,0.

A fix may be related to #3783 (but may be not).

Here's updated code: http://nbviewer.jupyter.org/github/birdsarah/bokeh-miscellany/blob/master/2822.ipynb (note this plot is only rendering sometimes for me - probably related to #3737)
