Fixes #10417 - Translate wizard states
Wizard states were shown after calling 'symbol'.to_s.humanize, whichdidn't allow them to be translated. I define the strings to be shownin the helper so that they can be translated.
Fixes #14244 - Update the strings to be more compliant with the project standards
Fixes #11984 - Update the plugin to use the latest gettext from core,and re-extract the strings.
Once this is merged, the project needs to be added to transifex.
Fixes #10416 - Pulled translations
