    #19: Port sheets/ to meson.
    
      - Use intltool to compile .shape from .shape.in
      - As per the FIXME, this should be replaced with i18n.merge_file()
      - Also move the echo statement from checktrans to checktrans.py
        - This is so we can call checktrans.py directly from meson and
          avoid having the extra dependency.
