Modules cannot be defined in configurations files

Problem/Motivation

As a way to give a lot of flexibility. Each configuration handler can define how to save its settings.

We are saving the required modules in the same file that all the other settings. The problem is that to be able to load this file, first we have to install the required module that allow us to read the file. And the instructions to load they are inside the file. Chicken-egg problem.

Proposed resolution

Move all the required modules to load all the configurations defined in tracked.inc inside the tracked.inc file.

Remove the $modules from the configurations files.
