Add some hello world which has all api imported to allow testing them all like it is done in SDK.

[GoogleCodeExporter]

Currently is only one:
import webapp2

We want:
import webapp2
from google.appengine.api import images
from google.appengine.ext import db
from google.appengine.ext import ndb
...
...

This will allow simple tests of API to learn how it works without any effort 
from your side.
