Trait and Scope definitions in 0.2.2 WD

[BBialeckiACR]

Specifically state that traits apply to components and scopes apply globally to an application. Settings in traits and components are essentially parameters themselves, but trying to have components opt in and out of a scope yet defining it at the application level burdens the Platform in parsing. There is a component level configuration which is trait that can be used and applied to multiple components in an application configuration.
