Add support for bundle localization

[izaera]

We must provide a way to configure the ResourceBundle of the OSGi bundle when creating JAR files from the bundler.

The configuration property will be at create-jar/features/localization and will point to a .properties file in the project (but excluding the the .properties suffix).

The default location is features/localization/Language and, if it exists, there's no need to declare it in .npmbundlerrc as it will be autodetected.

The properties must follow the standard defined by Liferay localization feature (i.e. standard Java locale files).
