Add i18n flavor template setting

A new setting, `flavorTemplate` is introduced to specify how strings are replaced with i18n representation. This includes code modifications for handling this new feature and also updates in the messages.properties file for the associated UI text. The feature is especially useful for customizing how localization strings are generated in different project setups.
