This reverts commit 3940c519 as
discussed in #1082.

* 'languagecleanup' of git://github.com/ptbrown/dokuwiki:
  Remove no longer needed language string
  Delete unused div (Fixes #1098)
  Remove unused language strings
  Move language string to authad plugin

PHP will localize floats (eg. a 45.5 becomes 45,5 in a German locale).
Using a string will prevent that. A fix has been applied on the server end,
but it makes sense to always send the correct message.
