- menu now use generic callback system, with extra data
- asyncMenuCall is removed in favor of launchAction
- menu_id (== callback_id) is used to identify menu instead of category/name/type tuple
- i18n is managed throught deferred translation, and returned with _i18n suffix
e.g.: menu (D_('File'), D_('Open')): (u'File', u'Open') is menu_path, (u'Fichier', u'Ouvrir') is french menu_path_i18n.
- type actually can have the following values:
- NORMAL: classical menu
- JID_CONTEXT: contextual menu, used with any jid
- ROSTER_JID_CONTEXT: like JID_CONTEXT, but restricted to jids in roster.
- ROSTER_GROUP_CONTEXT: contextual menu, use with groups
- security_limit is used, in the same way as for parameters
- when using importMenu, callback can be an actual callback, or one already registered with registerCallback
- _() 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)
