* Load translation strings suffixed with _js for a given list of modules.
* This function needs to be called when you want to i18n the user interface.
*
* How to use the function in smarty templates:
* {loadJavascriptTranslations plugins='SitesManager CoreHome General'}
*
* This will load the javascript translations array for the modules specified as parameters.
* Only translations string with their ids suffixed with '_js' will be loaded
* Note: You can specify disableOutputScriptTag=1 and the returned value won't be enclosed in Javascript tags.
*
* You can then translate strings in javascript by calling the javascript function:
* _pk_translate('MY_TRANSLATION_STRING_js')
*
* _pk_translate does NOT support printf() arguments, but you can call:
* sprintf(_pk_translate('MyPlugin_numberOfEggs_js'),'ten')
* where you would have the following in your translation file plugins/MyPlugin/lang/en.php:
* 'MyPlugin_numberOfEggs_js' => 'There are %s eggs.'
