Clean up class and method references

- In docs/api/cmd.rst, the `cmd2.Cmd` class was defined as `cmd2.cmd2.Cmd`, which required the extraneous `cmd2` every time we referenced it. This extra `cmd2` is no longer required.
- always refer to a bare cmd2 using ``cmd2`` per our documentation conventions
