hs project watch does not watch for added folders

[anthmatic]

Description and Context

hs project watch does not watch for the addDir event which can lead to confusion or errors when deleting a folder because we do watch for unlinkDir.

The other weird quirk here is that when you create a new folder in Mac Finder, it created a folder called "Untitled Folder" first and when you rename it, it deletes that folder and creates a new one. So 3 events reported for one "action".
