annotate src/core/i18n.py @ 771:bfabeedbf32e

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)
