Cleanup

[bfontaine]

I’m cleaning up the code by removing unused features and refactoring.

Stuff to remove:

• cursus’ managers (not used)
• reports (not fully implemented)
• search (unused, doesn’t search in contents)
• Piwik
• maintenance views (admin)
• user profiles
• course/cursus dashboards
• wontfix issues (close)
• download counts
• users_paths table
• events
• LaTeX processing
• keyboard shortcuts
• unused routes
• educational_paths
• news
• unused templates
• API routes (except those used internally)
• moderators
• unused JS files
• unused CSS files
• EIDD cursuses

Need feedback on these:

• Remove users and keep one “admin” account?
