core: i18n refactoring:

- _() is no more installed in __builtin__
    - instead, there is a new sat.core.i18n module
    - added D_() method for deferred translation
    - languageSwitch method allow to dynamically change translation language
    - import gettext is tested against ImportError, and dummy methods are used when not available (mainly useful for Libervia)
