* Smarty block function, provides gettext support for smarty.
*
* The block content is the text that should be translated.
*
* Any parameter that is sent to the function will be represented as %n in the translation text,
* where n is 1 for the first parameter. The following parameters are reserved:
* - escape - sets escape mode:
* - 'html' for HTML escaping, this is the default.
* - 'js' for javascript escaping.
* - 'url' for url escaping.
* - 'no'/'off'/0 - turns off escaping
* - plural - The plural version of the text (2nd parameter of ngettext())
* - count - The item count for plural mode (3rd parameter of ngettext())
* - domain - Textdomain to be used, default if skipped (dgettext() instead of gettext())
* - context - gettext context. reserved for future use.
*
* @param array $params
* @param string $text
