allow for clearing and removing individual toasts

[baseballlover723]

toastr allows you to individually clear and remove toasts, this change lets you do that. This shouldn't break anything since you can safely ignore the arguments for clear and remove. Manually tested on one of my ember apps.

I'll release a new version tomorrow. Thanks for the PR.

Published v1.5.0. I also added a toasts property to manage toasts.

Clear and remove doesn't really work for individual toasts, because Toastr.js checks if they are visible and does nothing.. see https://github.com/CodeSeven/toastr/blob/master/toastr.js#L458

let me take a look, because I was definitely able to clear an individual toast on one of my own ember apps.

[baseballlover723]

so I checked on my app, and it looks like removing an individual toast doesn't work, however, clearing an individual toast does work. One way to could be to call clear with a 1 ms hide duration when you try and remove an individual toast

[baseballlover723]

so, removing an individual toast doesn't work on the toastr library. I'm going to submit a bug report to them as well, but for now, this should have the correct behavior

remove(toastElement) {  
  if (toastElement) {
    toastElement.remove();
    this.get('toasts').removeObject(toastElement);
  } else {
    this.set('toasts', Ember.A([]));
  }
  window.toastr.remove(toastElement);
}
