FastGettext / Rails integration.

Translate via FastGettext, use any other I18n backend as extension/fallback.

Rails does: I18n.t('syntax.with.lots.of.dots') with nested yml files We do:
_('Just translate my damn text!') with simple, flat mo/po/yml files or
directly from db To use I18n calls add a syntax.with.lots.of.dots translation.
