Remove setting AUTO_INCREMENT's starting index.

The AUTO_INCREMENT does not seem to be necessary (MySQL can figure out
what IDs it can use by itself) and ends up being unnecessarily confusing
when new entries in an empty table start with an id that's not 1.

Also removed some of the manual setting IDs, since MySQL seems to be
able to automatically figure those out anyways.

Changed the 0000-00-00 00:00:00 datetime entries to use NOW() so MySQL
won't complain about invalid dates.

Capitalized all instances of AUTO_INCREMENT for consistency.
