Add Convenience class for handling Google's in-app billing

[GoogleCodeExporter]

Implement a system to handle Google's in-app billing in a simple way, while 
still allowing customization for those who wish to be more secure.

Added the GoogleBilling class. It uses v3 of google's in-app billing service. 
For this to work, you have to add <uses-permission 
android:name="com.android.vending.BILLING" /> to your project's AndroidManifest 
file. You will also need to create the package com.android.vending.billing, and 
put the IInAppBillingService.aidl file into the newly created package (you need 
to download Google's market billing from the SDK manager to get the aidl file). 
I'll probably add an option to add these to the project in a right click option.
