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
