[Subscriptions] User setting to automatically follow discussions you start/reply to

What needs to be done:

• Register a new bool preference (followAfterReply) using the RegisterUserPreferences event.
• Extend the core SettingsPage component's settingsItems method to add a new child to the notifications fieldset. That child should be a Switch which saves the followAfterReply preference.
• Listen for the PostWasPosted event and check the preference. If it's true, follow the discussion.

I started working on this issue. Its almost done but i have question about the implementation.

Referencing: flarum/subscriptions#6

Lets see subscriptions are managed in the subscriptions extension. I added 2 listeners here to add the setting and to listen to a new post. This works fine.
But now i want to add a setting to the settings page, this is also not that hard but the settings page is part of the core. So i would like to add some sort of addition to the settings page from an extension. Is there i method for this?

Example on how i implemented the settings now:

Add a new section to the settings list

    items.add('forum',
      FieldSet.component({
        label: app.translator.trans('core.forum.settings.forum'),
        className: 'Settings-forum',
        children: this.forumItems().toArray()
      })
    );

Implement the items under the heading

  forumItems() {
    const items = new ItemList();

    items.add('followAfterReply',
      Switch.component({
        children: app.translator.trans('core.forum.settings.follow_after_reply'),
        state: this.user.preferences().followAfterReply,
        onchange: (value, component) => {
          this.preferenceSaver('followAfterReply')(value, component);
        }
      })
    );

    return items;
  }

Everything works but i would like to move everything to the subscription extension.

@petermein Looking great so far! Thanks for taking this on.

I just committed a small change to core which will allow you to slow this switch into the "notifications" settings fieldset, right beneath the grid. I think this is the best place for it.

You'll want to create a new file in js/forum/src (something like addSubscriptionSettings.js) with something like:

import { extend } from 'flarum/extend';
import SettingsPage from `flarum/components/SettingsPage`;

extend(SettingsPage.prototype, 'notificationsItems', function(items) {
  items.add('followAfterReply', ...);
});

And don't forget to import it into main.js :)

Update the subscriptions PR, but i don't like the ordering of the settings items.
There is something with priority but im not sure yet.
