Pippo requires separate file for default language

[gkresic]

Per documentation at

http://www.pippo.ro/doc/internationalization.html

i18n is configured using application.languages setting in conf/application.properties and then having messages.properties with default language messages and one messages_<LANG>.properties file for each additional language configured.

However, it seems Pippo requires messages_<LANG>.properties even for default language. This can be seen when running pippo-demo-servlet which on startup prints:

13:49:00 [main] ERROR ro.pippo.core.Messages - Could not locate the 'en' messages resource 'conf/messages_en.properties' specified in 'application.languages'.
