Factory: Add 'CreateRunAndRelease' mechanism

[bartelink]

When building command processors which need to deterministically release dependent IDisposable resources, one often needs to perform a sequence as follows:

var handler = _kernel.Get( typeof(T) );
try
{
handler.Handle( request)
}
finally
{
_kernel.Release( handler );
}

It would be neat to have support in Ninject.Extensions.Factory to allow one to define an interface as follows and have it auto-implemented:

interface IHandlerFactory
{
void CreateRunAndRelease(Action action);
void CreateRunAndRelease(Type service, Action action);
}

Side note: This would probably build on a lower level Ninject.Extensions.NamedScope facility to create an IDisposable RAII ScopeBlock object (i.e., a proper reimplementation of Activation Blocks)
