Refactor "TreeDirNode.close()" method

Browse Source 
This method required adjustment to take cascades into consideration.

Since the arrow in the NERDTree window reflects the status of the
tail directory of the associated cascade, an arrow indicating open
status can be present when a higher directory in the cascade was
closed.

This commit will automatically close child nodes within the same
cascade of a closed directory node so that the arrow accurately
reflects what is rendered.
