- Fixed a bug where hook_site_post_install() was only firing off in unattended installs (i.e. via CI or Aegir) but not during manual attended installs (the post-install step was being put after the "Finished" page of manual install).
  - Watchdog logging output is now more verbose and the pre-install and post-install steps of install are now displayed on manual installs as "Starting installation" and "Finalizing installation" to make verifying that the hooks are working easier.
  - Added code to allow modules to use hook_module_implements_alter() to adjust the order that post-install hooks fire.
  - Tweaked PHPdoc comments to follow Drupal standards.
  - Added an additional API example for hook_module_implements_alter().
  - Clarified documentation wording.
