organic groups limits is broken code in og_global_limits.module - have a patch

I just updated my version of global limits, it was not working, if i had a number besides 0 or a negative it would not allow me to join a group that had a limit. so i went into the code dumped the very last function
function og_global_limits_can_add_more_members($group = NULL, $new_member_count = 1)
on the line that was passing false and found that $group did not have the
$group->og_global_limits_available_memberships assigned to it.
i went up to find out where it was assigned, in the case: load in
function og_global_limits_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL)
and found that it was assigning it there, but for some reason wasn't sticking. i had to patch it quick so i just changed the
og_global_limits_can_add_more_members function to this:

function og_global_limits_can_add_more_members($group = NULL, $new_member_count = 1) {
  if (is_numeric($group)) {
    $group = node_load($group);
  }
  else if ($group == NULL) {
    return FALSE;
  }

  $owner = user_load($group->uid);

+  $member_count = db_result(db_query("SELECT COUNT(*) FROM {og_uid} WHERE nid=%d AND uid!=%d", $group->nid, $group->uid));
+  $limit_override = db_result(db_query("SELECT lim FROM {og_global_limits} WHERE nid=%d", $group->nid));
+  $limit = variable_get('og_global_limits_' . $group->type . '_max_per_group', 5);
+  if ($limit_override !== FALSE)
+  {
+     $limit = $limit_override;
+     $node->og_override_limit = $limit;
+  }
+  $group->og_global_limits_available_memberships = $limit - $member_count;


  // first, take the easy way out if we can if the admin chose not
  // to limit the number of members that can be in a group or if the
  // group owner can exceed the limit or if the group owner set the
  // limit to 0 (which creates a negative available number)
  if (variable_get('og_global_limits_' . $group->type . '_max_per_group', 5) == 0 || user_access('exceed max per group limit', $owner) || $group->og_global_limits_available_memberships < 0)
  {
    return TRUE;
  }

  if ($new_member_count > $group->og_global_limits_available_memberships) {
   return FALSE;
  }

  return TRUE;
}

this appears to fix the issue i was having, but just so you know somewhere along the line its loosing the og_global_limits_available_memberships variable in the node. i haven't the time to track down where this is happening so for now if anyone else is having this issue, this is what i did to
fix the problem till a real patch could be released.
