[TASK] Use FLUIDTEMPLATE for rendering module Configuration

As cleanup and improvement for the backend it is important to remove the
HTML code from the PHP logic. This patch removes the HTML code and uses
StandaloneView to render the content of the module.

The markup was removed as far as possible.
