Redmine 5x compatibility

[whotopia]

I think one needs to change this:

#require_dependency 'redmine_introductions/hooks'
require_dependency File.expand_path('lib/redmine_introductions/hooks', __dir__)

perhaps there's more.

I'm also getting:

This plugin has been updated and is now compatible with Redmine 5.0. Can you please try the latest version and confirm that everything works fine?

Note that this plugin requires the installation of the redmine_base_deface plugin (https://github.com/jbbarth/redmine_base_deface) as a dependency.
