Implemented main module and plugin system

2 empty command modules are included: list and group. Their
implementation will be added soon. At the moment they're just printing
messages to the console.

Main module looks for subcommands using setup.py entry point group
'repa_commands'. This allows to develop and distribute extra repa
commands independently.
