Subject: [PATCH] Updated soypakcli.py

soypakcli is responsible for registering all commands, parsing and
invoking the command to run.

- global optional flags are explicitly check first, regardless of the
  number of args.
- if there is no command, the program displays the help message and
  dies.
- fetches the command class for the identified soypak command and
  initialised the class command.
- SoypakCLI@run_command: invokes the `run()` method of a command class
