add a path filter API

Add an API to allow custom "path filter callbacks" to be added.

Previously we allowed one path filtering function to exist called
`NERDTreeCustomIgnoreFilter`. This has been removed and replaced with an
API to allow any number of such functions to exist -  via the new
`NERDTreeAddPathFilter()`
