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
