Add support for "poor man's DI" (without container)

[BrunoJuchli]

Enable support for StaticProxy.Fody in scenarios where the user does not use a DI Container.

Ideas / Alternatives:

• Add an alternative to new by something like StaticProxy.New(() => new MyProxiedType(argument1, argument2), .. list of interceptors...) which, upon compilation, will be replaced by `new MyProxiedType(argument1, argument2, interceptors)
• same syntax but no IL-Weaving: use Activator.Activate to supply all parameters
  Use a syntax as in Ninject's ".ToConstructor" binding to specify
• other?

To progress, first investigate the constraints these alternatives have (for example, are there targets where Activator.Activate is not supported? Are Expressions supported?).
