First successful Ajax test

Ajax + Change folder structure from django_project to django
Moved images and document from django_project to django

Move images to new folder structure
Rearrange statics folder

Add 'js' subfolder in statics folder
Test db access

Added unit-testing of db access and added the folder "database"
Add Ajax test for "retrieve"

Ajax tests now include both store and retrieve.
They are still not perfect. I want to clear the test games before
writing into them, so that the test will always begin with an empty
game.
Also, I want to do refactoring to more easily add tests.
