Configuration language variables

[ez-plugins]

To make the configuration fully multi language something like language variables are needed to replace the messages in by example the countdowns.yml with language variables. This makes it easier for server owners to manage there configuration files.

Example variable

{translate:key.in.messages}

Gets translated from messages.yml

key:
  in:
    messages: "<b>String with formatting</b>"

Problem

With resetting the countdowns.yml the messages are gone, this way we can implement defaults to always get them from the messages configuration file.
