API changes:

require "gettext/tools/poparser" ->
require "gettext/po_parser"

require "gettext/mo"

GetText::MoFile ->

Support gettext 2.x again for Ruby 1.8

Gettext 3.0.0 drops Ruby 1.8 support but YARD doesn't drop Ruby 1.8
support yet. So YARD supports old gettext that supports Ruby 1.8
again.
