Generate a valid main.py for use with developer.android.com.

This fixes bugs in divide_and_compress_constants.py that caused a corrupt
main.py file to be generated for developer.android.com. Specifically,
extra quotes are no longer added, __main__ is now in quotes, and
webapp.WSGIApplication() parameters are now correct.

Also moved the call to memcache_zipserve.create_handler() to a seperate
line for readability.
