Tell Zend to not parse messages.po files

Zend tries to load messages.po files at every call. Let's avoid this,
since the files to be loaded are called messages.mo, but usually
developers keep their uncompiled version in place.

Please note that since parsing messages.po fails, they are not cached, so
Zend tries to load them at every page call.
Ignore also hidden files/directories

Load all translations with changeLocale

Currently, Localization::changeLocale loads only the core translations:

It's better to load all translations when switching the current locale,
since all the localization files should be considered as a whole.
