Curtain doesn't show if chart and map are both included

When you have the map and chart files both included in a document the "loading" curtain doesn't consistently show.

When you use both amcharts.js and ammap.js on the same page, instead of ammap.js you should use ammap_amcharts_extension.js.

ammap.js creates amChart's core classes which effectively overrides some of the Data Loader's presets/settings.

The curtain shows up fine if I make the above change:
