Added the nested keyword. Doesn't really add much new code.

Appears to work for recursively nested lists for free (although it gets ugly quickly). Is also compatible with the complex templates layout.

Syntax is:

{	
	list: 'listName',
	item: {
		//map
		nestedList: 'referenceToNestedList'
	},
	nested: [{
		list: 'nestedList',
		item: {
			//map
		}
		//whatever you can normally use
	}]
}

You have to copy the list over using the normal map at the moment. Adding a to: node would mean you could reference the source data and avoid this line. In two minds about whether that is a good idea.

Limitation is you can't reference anything outside the nested list. This has the potential to get messy if done wrong.
