GAE SDK update

Notable new features in this SDK are:

• Support for zipimport and a new module, zipserve, which serves static files from a zip archive. These allow you to work past the 1000-file app deployment limit.
• The development console now includes a memcache viewer (you can use this by accessing http://localhost:8080/_ah/admin while your app is running on the SDK).
• URLFetch now allows users to disable automatically following HTTP redirects.
• We now allow composite indexes with repeated properties.

It also includes the following issue fixes:

It correctly escapes path separators in static_dir path on windows.

Sending email messages with unicode content now works.

Fixed db.run_in_transaction so that it doesn't allow inserting two (or more) new root entities in a single transaction.

The new SDK is available for download, and as always, we welcome your feedback on the group!
