0.3.0

Introducing modes.
Backward incompatible changes

• --demo is replaced by a more general --mode argument,
  the equivalent being --mode=demo

• MARABUNTA_DEMO is replaced by MARABUNTA_MODE

• the configuration file has now operations and addons by "modes", allowing to
  load some different scripts or install different addons for different modes
  (the addons list are merged and the operations of the modes are executed
  after the main ones):

    - version: 0.0.1
      operations:
        pre:  # executed before 'addons'
          - echo 'pre-operation'
        post:  # executed after 'addons'
          - anthem songs::install
      addons:
        upgrade:
          - base
      modes:
        prod:
          operations:
            pre:
              - echo 'pre-operation executed only when the mode is prod'
            post:
              - anthem songs::load_production_data
        demo:
          operations:
            post:
              - anthem songs::load_demo_data
          addons:
            upgrade:
              - demo_addon
  

• --force renamed to --allow-serie

• MARABUNTA_FORCE renamed to MARABUNTA_ALLOW_SERIE

• --project-file renamed to --migration-file

• MARABUNTA_PROJECT_FILE renamed to MARABUNTA_MIGRATION_FILE

Improvements

• When 'allow_serie' is used, the same Odoo addon will not be
  upgraded more than one time when it is in the 'upgrade' section of
  more than one version

Fixes

• Fix error when there is no db version in the database
• Fix error AttributeError: 'bool' object has no attribute 'number'
  when there is an unfinished version
