Add 'strict_mock_calling' option

- By default set to true to maintain the default behaviour of CMock
  - When mocked function is called and no Except/Ignor called,
    test will fail
- When set to false:
  - if test calls mocked function,
    and user did not specify Except/Ignore/...
    test will not fail because of this,
    all calls to mocked functions are ignored
