Reducing memory usage of Google Contacts

Sorry for the silence for a few months. I've not had enough time to writing extensions. It still goes on but I'll update them little by little when I find time.

Now Google Contacts 0.6.41b1 is available. I found a possibility of memory leak and tried to fix it in the version. I don't know it can resolve memory usage issue reported many users completely. But I'm glad if you can test it and post a comment here.
