/**
 * 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.
