Make sure all existing tickets in TRAC are properly defined #608

That would be great if all tickets in trac were properly defined:

• component (core/ui/documentation/website) most of them are core, some would be mix of core and UI, we use good sense to assign to either core or UI
• type should be set to either Bug, New Feature. I deleted "Task" from now as it's not clear to me what is task VS new feature. This ticket would be ideal for a "task" but there are too little of them to have a category.

This is useful because then we can build list of opened bugs, opened new features, etc. that are actually complete. An example is on the contribute page where we invite people to look at "open bugs" or "open feature requests".

I think currently the classification in milestones is pretty good. We may revisit soon to make the "digital vibes" smaller, but ok for now.
