Ignore paths option

[tanepiper]

Consider that I have a folder structure like this:

myfolder
    - output
    - source
    - theme
    config.json

I'd like to put a watcher on the whole myfolder - but I want to ignore changes in the output folder - ideally when setting up I can do the following:

watchr.watch({
  paths: [
    'myfolder'
  ],
  ignoreFolders: [
    'myfolder/output'
  ]
});

This is a real good idea.

I'd like to see this accomplish via hooking into the scandir action callbacks, allowing us to actually have a function where the callback err, ignore determines if we should ignore the directory. Something like:

watchr.watch({
  // ...
  events: {
    watchBefore: function(fullPath,next){
      return next(null, /myfolder\/output$/.test(fullPath))
    }
  }
})

Something like that at least. Would you want to tackle this as a pull request?

Added in v2.3.3 via the ignorePaths: ['/Users/balupton/super-secret-file'] option. Thanks!
