Customization of the display

[Wadeck]

In order to support any kind of configuration, the display in the popup must be configurable.

Example : a developper only uses the plugin to switch database, he will desire for sure customize the view on the config file. Only the database arguments are relevant for him.
Another developper uses some custom argument to activate modules, only thoses lines are interesting for him even if there are lots of "little" configuration details in the files
