Add Delegate Templates support

[lincolncooper]

Would it be possible to add support for Delegate Templates so as to be able to specify the Package name(s) and call the setActiveDelegatePackageNames method?

I've read about delcall/delpackage but have not personally used it (yet). I know with the current release of Silken it's not possible to use these at the moment as their is no way to pass through/set the appropriate delegate package names (i.e. setActiveDelegatePackageNames());

It would however be a minor code change to support this. It could be done in one of two ways:

1. By providing a new Resolver similar to runtimeGlobalsResolver. A method on the resolver would return/set the package name(s).

2. By passing through/setting a request attribute that defines the list of names. e.g.

req.setAttribute("model", boatPojo);
req.setAttribute("active_deligate_package_names", ImmutableSet.of("MyDeligate");

3. Or implement both, because it will be hard to predict how it may be used in the future.

I'll have a think about this and also see out some input from others. I'm going to make a few enhancements to Silken soon and will make these changes in this work.
