This change updates x52test to use the gettext APIs. This also adds a
fake message catalogue to verify that the code is converted correctly
and the translations are displayed.
The fake message catalogue translates the English strings into Pig
Latin, which makes it easy enough for a maintainer to verify that the
changes have been made correctly.
Finally, this also adds some documentation to tell the maintainer or
translator how to make the relevant changes.
