If node isn't open, count children on disk before deleting.

Browse Source 
Fixes #821. If a node isn't opened in NERDTree, it's children aren't
known yet, so when deleting the node (with `m`, `d`), the user isn't
properly asked to confirm the delete. It was going to the less strict
`Y`/`n` confirmation, instead of the `yes` confirmation for non-empty
directories.

This change checks to see if the node is opened already. If it is, the
existing getChildCount() function is used; otherwise, the disk is read
to get the number of children there.
