[TIMOB-24412] handleCustomView in AnnotationProxy (ti.map)

In https://github.com/appcelerator-modules/ti.map/blob/master/android/src/ti/map/AnnotationProxy.java#L224 I see a little issue: toImage() creates a KrollProxy, but the statement aspects a blob. http://builds.appcelerator.com.s3.amazonaws.com/javadoc/org/appcelerator/titanium/proxy/TiViewProxy.html#toImage() I see an error in IDE, but I can build the module. Not tested, but this is redfree: TiBlob imageBlob = (TiBlob)((TiViewProxy) obj).toImage().get("media");
