The new manage.py upgrade command takes care of running syncdb and

evolve, running both in the same session so that we can take advantage

of the new protection from extension database modifications interfering

with the upgrade process.
This new command is also more helpful, providing confirmation before

making any changes, and automatically backing up the configured SQLite

database (if used) so that the user can easily revert back. The backup

is stored at the location of the original database, with a timestamp

appended.
Backup behavior can be turned off with --no-backup, and confirmation

can be turned off with --noinput.

Tested this with default behavior on SQLite3 and MySQL. Verified that

upgrades occurred with SQLite3.
Tested both --no-backup and --no-input.
