Plugins system broken?

[Apfelwurm]

Describe the bug
Hello, i'm pretty new to ruby and fab-manager, but i want to try to implement a plugin for it.
Sadly it seems that the repository of the sample plugin is outdated and does not really represent a working plugin anymore.
The error i get when trying to use the sample plugin:

NoMethodError: undefined method `assets' for #<Rails::Application::Configuration:0x00007f1cb0c5be20 @root=#<Pathname:/workspaces/fab-manager>,

(See full trace by running task with --trace)

It seems the plugin (system) did not get updated with newer ruby versions?

To Reproduce
Steps to reproduce the behavior:

1. clone https://github.com/sleede/navinum-gamification to your plugins path
2. run rake navi_gami:setup or just foreman
3. See error

Expected behavior
Plugin should migrate and do its stuff
