add blacklist as path

[timaschew]

Would be nice if the filter would support a path (or array of paths) which is blacklisted instead of white listed.

+1, this is how I expected it to behave. Using a ! would be a nice way to do it without changing the api

@tyrsius I was for this at first, but that doesn't make a ton of sense now. If you mix blacklist and whitelist, how do you know what to save?

I think an argument to pass as a second parameter makes more sense.

{blacklist: true} or whatever
