Modified library to work with GoogleAppEngine

This will allow for the current android library to work on GoogleAppEngine - I have made two major change:
1. I have replaced the HTTPClient methods from org.apache with the java.net HTTPUrlConnection methods. 
2. Any java.awt images methods were replaced by the Images API methods of GoogleAppEngine.
As per my other pull request, the library here has been changed so that places with more params, like "website", can be added.
