[TIMOB-12835] BlackBerry: ActivityIndicator sizing and positioning incorrect.

The sizing and positioning of indicators isn't correct. They always appears small and don't get properly laid out in their parent.

Test Case

var win = Ti.UI.createWindow();

var ind_absolute = Ti.UI.createActivityIndicator({
	width: 100, height: 100,
	top: 5
});
win.add(ind_absolute);
ind_absolute.show();

var ind_auto = Ti.UI.createActivityIndicator();
win.add(ind_auto);
ind_auto.show();

win.open();

Expected: Should see two indicators. One should be near the top and large. The second indicator should be near the middle and smaller in size.
