Plugin config options as object and new onTranslationNotFound method
This version has several fixes:
- The minified file version is now actually a minified version of the umd version
- There will be a warning, if the locale is not specified when a translation key is used
- Plugin initialization options can now be set via an object. A depreciation warning is shown for the array initialization method
- There is a new plugin option onTranslationNotFound. This is a method that will be called if the translation key is not found in the current locale. Albeit the translation might still be available in a localized locale or the fallback locale.
