Breaking changes

PHP >= 5.4 compatibility (dropped PHP 5.3 support)
New class Merge, that changes the way to merge translations.
Gettext\Translation::getPluralTranslation() renamed to Translation::getPluralTranslations() and always returns an array with all plural translations
Removed the print functions like __e(), n__e(), p__e(), etc. Use <?= __('text') ?> instead.
The format PhpArray has a different structure
Removed Gettext\Translation::normaliceTranslationCount() to improve performance
Removed Gettext\Translator::initGettextFunction(). Use $translator->register().
Invalid languages throw a InvalidArgumentException in Translations::setLanguage()
If not specified, the default domain for translations is an empty string instead "messages"
Changed the extractor and generator interfaces and allow to pass an array with the options instead use static properties.
Removed the ability to include empty translations on generate Mo.

Added the $checkContent argument to Translation::hasPluralTranslations() to check whether the plural translation contains any text or not
Added Translations::$options to configure some default headers.
Prevent to insert duplicated comments, flags and extracted comments in a translation
Translations::register() returns the previous registered translations instance if exists.
