Policy-based or convention-based composition configuration

[iravanchi]

If the "External composition configuration" feature is implemented ( #25 ) there can be policy-based configurations that specify general rules (rather that individual components and configuration).

Examples include:

• All non-abstract classes that inherit from class X are components
• All classes in the assembly X that their name end in Controller should be [Transient]
• Consider all constructor parameters of component in assembly X as optional
• All properties of classes in namespace X should be treated as [ComponentPlug]s
