vote_up_down 6.x-2.2

Release notes

Changes since DRUPAL-6--2-1:

• bug #890404 by Agileware, marvil07: Avoid array_merge_recursive() on hook_votingapi_results_alter() function.

  New aggregation functions for votingapi cache table were assuming there
  will be only one tag, that's now fixed.

  In the other side, we are now avoiding use array_merge_recursive() and
  instead, add the values directly to the $cache array
  fix aggregation functions for positives/negatives so they calculate all tags results instead of only one tag result

  This patch also move the logic again to the
  hook_votingapi_results_alter() function.

• #815984 follow-up by marvil07, droplet: Make widgets readable by screen readers for all missing widgets.
• #880014 follow-up: use the right votinapi tag name on vud_comment hook_link
