Subject: [PATCH] Restore getDirChildren for use in nerdtree-project-plugin.
 (#929)

This function was added to support a separate plugin:
https://github.com/scrooloose/nerdtree-project-plugin.git. It was
subsequently removed without recognizing its contribution to the
external plugin. This commit restores that function so NERDTree projects
will work.
