Getter for XmlNodeList objects

[Pxtl]

Lets you use {{foo.1}} to get the 2nd foo in

<foo>first</foo>
<foo>second</foo>
<foo>third</foo>

Redundant with XPath queries, but makes it consistent w other getter syntaxes.

• XmlNodeListGetter to pull from lists by index, similar to IList getter
• XmlNodeListGetterFactory to create above
• Tests for above.
