It's quite tangled (again). Localization's kind've half in System and
half in GetText.

What seems like it might work is to gut GetText - leave the UI
components in it (so the GetText-Editor system category) - and move
GetText-Localization (GetTextTranslator, MOFile, TextDomainManager)
into System-Localization.

(As a side note, TextDomainManager >> #domainForClass: looks broken.
It simply returns 'etoys'. So either it should move to the Etoys
package, or it's half implemented and needs finishing off.)
