Revert gettext stuff.

Keep english values for language keys translation.
Provide a script to use english values for key in language files.

Todo : provide a script (to help transition) to keep using
original keys in language files for translators.

-/**
- * Provides a simple gettext replacement that works independently from
- * the system's gettext abilities.
- * It can read MO files and use them for translating strings.
- * The files are passed to gettext_reader as a Stream (see streams.php)
- *
- * This version has the ability to cache all strings and translations to
- * speed up the string lookup.
- * While the cache is enabled by default, it can be switched off with the
- * second parameter in the constructor (e.g. whenusing very large MO files
- * that you don't want to keep in memory)
