Remove support for deprecated concept names

[Ndpnt]

In the version 0.7 there are the following renaming:

• Hook → Locator
• Widget → Component
• Data → Fixture
• Feature → Scenario
• scenario → steps (inside Scenario)
• Flow → Verbose

Support for previous concepts names have to be removed in the major release v1.0
