jp: refactoring: - imports from sat_frontends.jp instead of local imports - added __init__.py - commands now inherits from a base class: each base.CommandBase instance is a subcommand - new arguments are added in CommandBase.add_parser_options methods, starting point si CommandBase.run or CommandBase.connected if a profile connection is needed - commands are exported using a __commands__ variable at the top of the module - sub-subcommand are easily added by using an other CommandBase instance as parent instead of using a Jp instance. In this case, the parent subcommand must be the one exported, and have a subcommands iterable (see cmd_file or cmd_pipe for examples). - options which are often used (like --profile) are automatically added on demand (use_profile=True, use_progress=True) - commands are automatically loaded when there are in a module named cmd_XXX - restored --connect option - restored progress bar - restored getVersion bridge call on jp --version - fixed file and pipe commands - fixed forgotten translations - fixed non SàT compliant docstrings - better about/version dialog
