Default Quiet/Argument Options to None

[derks]

To be changed in Cement 3.2.0.

The framework should be as minimal as possible by default, and setting argument options by default isn't ideal for that. This can still be setup in the project template, however the options in the framework should default to None:

class App(object):
    quiet_argument_options = None
    debug_argument_options = None
