Title: fix type and smart close single child directory

fix type 'Casade' to 'Cascade'.

While press 'x' to close parent dir, NERDTree would also close its grandparent dir if parent is the only child of grandparent.

Because the option 'NERDTreeCasadeOpenSingleChildDir' is default on, so almost nothing need be changed.
