Improve UI

• [x] Refactor fact-check results to 4 categories (definitely true, possibly true, definitely conflicting (false), not enough info)
• [x] Allow smoother interaction between fact-check result and updating kg
• [x] Fact check with article url
• [ ] If insert/check triples, should they be checked if they exist in DBpedia by backend?
• [x] Entity explorer (can add/remove triples for the entity)
• [x] Add own triples (also by submitting sentences? -> not yet)
• [ ] Lookup entity and relations?
• [ ] Edit pending triples -> difficult to do
• [x] Remove the conflicting triples
• [x] Extraction scope and auto add toggle
• [ ] Look articles? -> not necessary?
