Bugfixes

Fixed a bug which affected retrieving translations.

getTranslated + getDefaultLanguage

Changed the getTranslated method so that it checks for model's default language and lost the default value parameter.

Add getTranslated method

Added getTranslated method to the Translatable trait.

Optimize, simplify, refactor

• Removed the constraint of the translation being "fresh" in method translation
• Translations will now be updated instead of just creating a new one for every translation
• Added new method getTranslationsAsArray

First release!

Creating translations manually + translate and detectLanguage methods from external translation services.
