Added a colour ID TreeView::selectedItemBackgroundColourId, and changed the TreeView to fill selected items with this. (The colour is set to transparent by default so this won't affect existing code).

Updated the LookAndFeel::drawTreeviewPlusMinusBox and TreeViewItem::paintOpenCloseButton methods to provide more flexibility.
