New messages and notification sound selection menu.

Now, the notification sound can be selected from a menu. The configuration of whether to keep the list of sounds or to use the menu can be done from the config.yml file.

Also, a problem that I discovered during tests has been fixed, which was that when the plugin was reloaded, it did not add the notification sound to online users in the userdata.yml file. Now the code works fine.

All console messages were also removed.

Today i see a little error in code, so in this update i fix it. You don't need do nothing important, only if u want, update.
I recommend update it, but you can don't update.

In this update, the language files get a new template:

Now, all the messages has their category and the help menu appear now in their language file.


Too, now each language has their language name. This is for the command /motd+ language. When u set a language, now appear the language's name. For example, if u set english, before appear en-US, now appear English.

IMPORTANT
I recommend reset language files.
Too, delete the sound part in config file. If you don't do this, the sounds don't appear in the config file.

In this update, i add custom notification sounds.

Now, the config file change for sounds; the file contains now a sound list, available for all users.

IMPORTANT
Reset the config file deleting all the part for sounds, or backup the old config file and delete or rename it.
The languages file too change, do the same.

This new version bring:
- New update checker: receive a notification in...
- When the skript is loaded, console receive a notification with the new version.
- Too, when a user with permission mentionpro.admin join, receive a notification.
- Fix when an user disable all individual notifications, global notification don't disable. Now, the global disable automatically.
