RadarView crashes with NPE if there is no worldListType = 0

[gb96]

java.lang.NullPointerException
    at com.beyondar.android.plugin.radar.RadarView.drawRadarPoints(RadarView.java:69)
    at com.beyondar.android.plugin.radar.RadarView.onDraw(RadarView.java:60)

Looking at RadarView.java I see the code is attempting to iterate over worldListType using an int counter starting at zero, causing the NPE if there is no worldListType=0 defined. Safer to just use Java collection iterator (or for-each loop) here, the int counters are not required.

// in RadarView#drawRadarPoints(Canvas):
for (int i = 0; i < mRadarPlugin.getWorld().getBeyondarObjectLists().size(); i++) {
    BeyondarObjectList list = mRadarPlugin.getWorld().getBeyondarObjectList(i);
    for (int j = 0; j < list.size(); j++) { // line 69, NPE here when list == null
        BeyondarObject beyondarObject = list.get(j);
        RadarPointPlugin radarPointPlugin = (RadarPointPlugin) beyondarObject
                .getFirstPlugin(RadarPointPlugin.class);

Easily fixed (and more elegant) using Java for-each loop instead of dodgy int indexes like this:

// in RadarView#drawRadarPoints(Canvas):
for (BeyondarObjectList list : mRadarPlugin.getWorld().getBeyondarObjectLists()) {
    for (BeyondarObject beyondarObject : list) {
        RadarPointPlugin radarPointPlugin = (RadarPointPlugin) beyondarObject
                .getFirstPlugin(RadarPointPlugin.class);
