Sometimes we return different content depending on whether JSON, XML or
HTML was requested in the Accept request header. The Vary response
header should list that header in these cases, to allow caching
frameworks to determine what to cache.
- Prevent feed access to restricted profiles
- Rework display of restricted profiles with a redirect to the profile/restricted route
- Normalize permission checking with IHandleUserSession->isAuthenticated
- Remove unusable "nocache" parameter in feed module because session isn't initialized
- Reword setting name and description
- moved constants GRAVITY_* from boot.php to Friendica\Model\Item
- also rewrote some array initialization:
From:
````
<?php
$arr = [];
$arr['foo'] = "FOO";
````
To:
````
<?php
$arr['foo'] = "FOO";
````
- added a few type-hints
- Add all dependencies, necessary to run the content (baseUrl, Arguments)
- Encapsulate all POST/GET/DELETE/PATCH/PUT methods as protected methods inside the BaseModule
- Return Module content ONLY per `BaseModule::run()` (including the Hook logic there as well)
