[IronPython] StaticResources + DLR + Silverlight

Hi Jimmy,

I was reading your blog and it turns out you and I are the same age. Go figure.

I tried this out, and it works great. There's one major problem with
it though. It doesn't work with templating. LoadComponent has no
overload that accepts a xaml string (or loaded application object).
The current workaround I'd have to use is to evaluate the template,
upload the generated xaml to the server, get a dynamic uri back, and
load the xaml back down with LoadComponent. Very nasty. Please, please
push to get an lower-level overload of LoadComponent that takes xaml
instead of a Uri (probably there already is such a beast, it's just
not public.)
