Updated style, drupal standards.
Updated compare tag functionality.

  - Log results during hook_buildmanager_build
  - Simplify tags so annotated tags don't look different than regular tags when
    using ls-remote-tags (git ls-remote --tags)

Fixed checks on hook_buildmanager_build.

  Projects were getting checked twice, the second time was duplicative and
  unnecessary.
