Add clientside prs and issues tracking

[DarkMrMelther]

Added badges and titles for issues and prs into the tracker.
It works this way:

• The client calls the GH api for the issues (PRs are considered a type of issue in the api)
• For each issue it checks if contains the class name as a whole word (case insensitive)
• It stores the issue in the class model
• That's it 👍
  It depends on the client (and GH) how fast the issues and prs appears tho

could we store the tags in a database?

We already had a huge PR by filou and evald (#11) that did this with a db and logins but 4lve wanted to keep it minimal, so he rejected it (so no, possibly some time in the future tho idk)
