helpers: Add new helper xfce-open-gitlab
This helper enables you to quickly open the GitLab project of your Git repository in your browser when working in your terminal. You can navigate to a subpage by supplying that as an argument (e.g. "issues").
Note that the GitLab groups supported right now are
- xfce
- panel-plugin
- thunar-plugin
- apps
