Update README.rst - "attributes" is not a strategy (Closes #204).

The wording of the readme suggested that "attributes" is a strategy just like "build" and "create", but this is not the case in the implementation (for example keyword arguments do not work, SubFactory fields don't behave as expected), so I have removed the mention of this and replaced the attributes example to mention the "stub" strategy.
