Dashboard custom buttons

Implement #17 (closed): Custom buttons for dashboard

Update fontawesome dependency to version 5

• less dependencies (no more select-2 and special jQuery version)
• current icons
• admin widget working

The update required changes in the templates (new template tag and version 5 introduced namespacing for styles)
