Add url property to BlobStoreFile and BlobstoreUploadedFile.
This makes the FileField's ClearableFileInput widget show up properly when there's an existing file in the model.
Patch manage.py test to enable file uploads to blobstore.
Streamline the last checkin a bit by automatically pulling up the blob content-type, blob-key, and name.
Add testing of File fields that store BlobstoreFiles
Update to work on SDK 1.7.6
Force use of devappserver2 by putting a file in the root of your project called force_devappserver.py
The file should contain a single variable:

devappsever_ver = 1 or 2

manage.py runserver, test and remote shell commands work on both devappserver1/2
manage.py shell works on devappserver1 but not devappserver2.
Other commands have not been tested.
