missing in some translations

this was lost because the subscription branch, branched before this
change in master

now the data parameter, which really is a timestamp is only handled
internally of the subscription class

merged the wrong change here

  - removed some dead/unused code
  - fixed phpdoc

resulted in no further indexer tasks being run.

Fix case-insensitive match in ACL checking

ACL checking of DokuWiki is currently always case-sensitive
regardless of auth backend setting ($auth->isCaseSensitive).
This commit enables case-insensitive match in the same way
of auth_isMember().

Ignore empty email headers

Empty BCC/CC headers may cause errors on IIS.
