Plugin not prepared for translation

[robertoschwald]

It seems some entry points are missing to prepare the plugin for translation:

1. Text Domain declaration

* Text Domain: security-headers

is missing in readme.txt and in http-headers.php

2. load_plugin_textdomain() missing

function security_headers_text_domain() {
    load_plugin_textdomain('security-headers', false, basename( dirname( __FILE__ ) ) . '/languages/');
}

is missing in http-headers.php

3. Using Gettext
   Texts are hardcoded in http-headers.php. Should use __('Default String', 'security-headers')

4. Create languages dir

5. Current repo?
   I'm not sure which one of the repos are the current one. This one on GH, or
   https://plugins.svn.wordpress.org/security-headers/
