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.
Hello, I was thinking of making the default constructor to be DefaultRequestHandler() however, I have gone and customized your library for GoogleAppEngine which means that I have used classes such as com.google.appengine.api.images.Image and import com.google.appengine.api.images.ImagesServiceFactory to replace your awt.images code - see changes made in the Photo.java class. 
A person who wishes to use this library on GAE can therefore not easy just substitute their requestHandler for the GAERequestHandler and make it work on GAE....Would you be able to pull this request to a new branch on your side for a separate library just for GAE?
