KS-4386: Performance on navigation
* When creating new tree node for a page, don't push all level descendants into it. To do that:
* Create a new function named getDescendants is used to return a tree node which already contain all descendants
* Change the function getTreeNode to return tree node only
* Change to use getTreeNode function in PageTreeMacro
Some minor improvements:
The page tree macro should show the first level of children by default
The loading animation of tree should be smoother by adding "loading.."
