[FEATURE] Adds the classicDecorator option (#132)

Adds the `@classic` decorator if the option is enabled to every class.
The option is enabled by default.

I also cleaned up some of the organization of the tests, and the way
option defaults were setup. Now we have a single location where options
are defined and enabled.
