Remove add_reasons_to_defaults() from general initialization (#627)

* Remove `add_reasons_to_defaults()` from general initialization

The `add_reasons_to_defaults()` adds the translatable strings to the `$default`.
Those `reasons` are only needed inside the `send_mail_notification()` method,
which also calls the `add_reasons_to_defaults()` function. Therefore, the function
call can be removed from the general `init()` function.

* Remove `load_plugin_lang()` function and utilize `_load_textdomain_just_in_time()`

This function is calling the `load_plugin_textdomain()`, which eventually become
deprecated soon. Since this plugin is also using the "Text Domain" plugin header,
it is not necessary to call this function at all.

By removing this function, the `_load_textdomain_just_in_time()` function will be
used, when the first string needs to be translated.

* Add an action to load the reasons on `init`

* Raise "Requires at least" version to 4.6

Since we don't explicitly load the translation files anymore
this will make sure that the necessary function is there.

* Fix PHPCS issues

 Antispam Bee works best with default WordPress comments. It is not compatible with Jetpack, wpDiscuz or Disqus Comments as those plugins load a new comment form within an iframe. Thus Antispam Bee can not access the comment form directly.
 
 ### Does Antispam Bee work with AJAX comment plugins or similar theme features?
-Whether Antispam Bee works with a comment form submitted via AJAX depends on how the AJAX request is made. If the request goes to the file that usually also receives the comments, Antispam Bee could work with it out of the box (the [WP Ajaxify Comments](https://wordpress.org/plugins/wp-ajaxify-comments/) plugin does this, for example).

 If the comments are sent to the `admin-ajax.php`, the `antispam_bee_disallow_ajax_calls` filter must be used to run ASB for requests to that file as well. If the script does not send all form data to the file, but only some selected ones, further customization is probably necessary, as [exemplified in this post by Torsten Landsiedel](https://torstenlandsiedel.de/2020/10/04/ajaxifizierte-kommentare-und-antispam-bee/) (in German).
