Crash when application left open on Saved Game list

[GoogleCodeExporter]

Tested Revision 227:
I was playing with Mathdoku and had the saved game list open. I then switched 
to another application, did some other things on the phone for around 10 
minutes and then tried to go back to MathDoku, but it crashed.

I was able to reproduce shortly afterwards by repeating the steps.

I tried on another phone and was able to reproduce it. I tried on my HP 
Touchpad and wasn't able to reproduce it (but I didn't try that hard!)

Attached is an annotated log from the phone during this period

Good testing and good description of what is happening.

The log contains following message which is crucial:
    Unable to resume activity {net.cactii.mathdoku/net.cactii.mathdoku.GameFileList}: java.lang.NullPointerException: UsageLogging can not be retrieved if not instantiated before

The onResume of the GameFileList:
    protected void onResume() {
        UsageLog.getInstance();
        super.onResume();
    }

while in MainActivity:
    public void onResume() {
        UsageLog.getInstance(this);
                ...

I am not sure if I can reproduce your problem but I will fix the onResume 
method of the GameFileList anyway.
