That change is done to be compatible with the phpmyadmin translator
class so this can be a drop in replacement or other way around.
Update smarty block.t to only check for _* functions and not any pre
loaded language class
__pn for context plural has now correct name __np
Update smarty plugin block.t.php to use __* named gettext methods for
all calls, for __n/__np/__/__p calls we fallback to check internal set
class on l10n object variable.
This will be removed in future calls
