Consider means by which private constructors could be selected (perhaps by overriding
methods in ReflectionActivator.)

I would certainly like to see this feature implemented even though it may seem like a
bit of a fringe case on the surface. I have done some testing and have been able to
include the functionality with very little effort. Here is what I changed.

• Added a SearchAllConstructors method to the IReflectiveRegistrar, IGenericRegistrar
  and IAutomaticRegistrar interfaces.
• Added a SearchAllConstructors property to the IConstructorSelector interface.
• The boolean value is set on the constructor selector by the method on the registrar.
• The ReflectionActivator uses the value to choose the binding flags to use.

I went with a Boolean value as if you exclude static constructors and class
initializers then all that is left are public instance constructors and non-public
instance constructors.

The reflective registrations appear like this:

builder.Register(typeof(Foo))
.SearchAllConstructors()
.FactoryScoped();

The generic registrations appear like this:

builder.RegisterTypesAssignableTo()
.SearchAllConstructors()
.FactoryScoped();

The default flags remain Public and Instance. You probably already have something in
mind for this, but if you’re interested I have attached a patch. Maybe you can come
up with a better and more fluent sounding name for the method.

Thanks for the patch Alex.

Had a quick look through, looks good. I'll try to spend some more time with this
soon, I'm planning to do a bit of refactoring in this area.
