Upgrading from Drupal 7 alpha 6 to Drupal 7 beta 2

This isn't pretty. And i've probably left out a critical step.

Core concepts: making some changes directly in the database. Enabling head2head and alpha2alpha in the database (setting both status and schema_version). Manually commenting out the update hooks that i did in the database to make user module's updates work so that alpha2alpha's can work.

Setting the line in alpha2alpha.module to give the current version:

<?php
  $version = variable_get('alpha2alpha_version', 7);
?>

and then change the 7 to 8. Rather than the default FALSE.
