[development] $book_node->parent blues

[Bèr Kessels]

Hello

Apparently 'parent' is a reserved word, yet we use a 'parent' in our books. A 
node in a book has a $book_node->parent that contains the NID of its parent. 

I came across this when checking if a node is in the book, I wanted to see if 
$book_node->parent isset. After an hour of frustration, dprinting and so, I 
found that that is actually set, but that one cannot refer to it.

As I can hardly beleive that I am the first to bump into this: Am I missing an 
obvious point? Is there an issue for this if it really is like this?
