XmlDeserializer issue not handling lowercase + dash root elements in some cases

Issue description in this post:
https://groups.google.com/forum/?fromgroups#!topic/restsharp/xww5tH0QAC0

Quoted here:
I'm writing a wrapper for BaseCamp API and ran into an issue.

The xml I'm getting back has this structure:

<todo-lists>
<todo-list>
</todo-list>
</todo-lists>

The problem is in HandleListDerivative since it does not try the
lowercased, "undashed" version for element names.

What I don't know is that what is the idea behind on operating on
Descendants when deserializing a list and not operating on children
nodes only?

Adding this code fixes this problem:

if (!elements.Any())
{
var lowerName = name.ToLower().AsNamespaced(Namespace);
elements = root.Descendants().Where(e => e.Name.LocalName.RemoveUnderscoresAndDashes() == lowerName);
}

Willing to accept a pull request with an associated test on this from anyone that wants to take it on. If you do, comment here so I can close this issue.

There's an associated unit test now, however I think I'm not doing the right thing by merging from my master branch.
Want me to reapply the fix from a feature branch?

I ran into this problem using RestSharp (deserializing an array where the object type is "MyElement" and the xml element name is "my_element" doesn't work) and I would very much like to see this fix in the official distribution.
