Starting work on 1.7.7

Noticed the header's slightly changed for the User module for login.  Also, there's a new dev_appserver.py script of which I haven't found the major difference.  However, moving back to the old_dev_appserver.py file seems to work (basics at least, no datastore).  I had to patch the appengine sdk and remove a check for a configuration struct (of which I haven't figured out how to pass in the right values).

I wanted to look into why it wouldn't work, and this is as far as I've gotten so far.
