I Refactored the code so that the file structure is easier for further evolutions.
Moved most of the directory in /app.
Moved routes in /app and not in /utils.
Prepended routes that returned json by /api.
Fixed a bug that reset the user settings when clicking on "Save".
The settings will now not be created if not put in the request but it avoids them being overriden by empty string as it was before.
Added a new route that allows to retrieve the ports in a json format (can be useful later to create some agent that would need to compare ports between Portall and the monitored machine)
/api.
