About plugin internationalization

Hi @brianmcculloh,

I want to translate this plugin to Spanish, but I noticed some issues that you should fix before:

• Do you need to add the text domain meta-data in plugin header:

  /*
  [...]
   * Author: Well Done Marketing
   * Author URI: https://www.welldonemarketing.com
   * Text Domain: worth-the-read
   * License: GPL2
  [...]
   */

• The text domain you’re using in translation functions is 'wtr', but your plugin slug is 'worth-the-read' (the whole sentence). You need to use 'worth-the-read' as text domain to enable the plugin translation in GlotPress. You can learn more here
• Do you need to wrap inside internationalization functions these strings located in wtr-config.php file: :247,:248,:249,:289,:293,:297,:301,:356,:360,:364,:368,:507,:508,:541,:542,:543,:592,:593

Hope this helps you to improve your plugin.
