// Puts i18n in filter mode - this allows you to have multiple default/per locale
// values for one key and to use one of them based on the filter parameters.
// Let's say you added a new column "message_variant" to your i18n table.
// Now you can have keys that will translate to a language differently depending on the used variant
// For example you have 2 rows in you table for key X, language EN, different values and different "message_variant" (let's say 1 and 2)
// If you want the solution to use the first variant, you will have to call:
i18n.setI18NMessagesFilter('message_variant', '1')

// ATTENTION: if you use setI18NMessagesFilter(...) it is not recommended to use the i18n Dialog (especially before the filter is applied through JS).
